Allergies

There are a few things to keep in mind regarding allergies. First, allergies fall into two categories: environmental and food. 

Pollen, mold, dust, or other irritants in the air cause environmental allergies, while ingredients in your dog’s food cause food allergies. 

Second, it’s essential to know that allergies can cause a range of symptoms. These symptoms can include itching, redness, swelling, hot spots, hair loss, and more. 

Third, if you suspect your dog has an allergy, you must talk to your veterinarian. Your vet can help you determine the allergy and develop a treatment plan.

Annual checkups

Your dog can’t tell you when something hurts. That’s why annual vet visits matter so much. A yearly checkup isn’t just a formality. It’s your vet’s best shot at catching problems early, before they become expensive emergencies.

Adult dogs (ages 1 to 7) need a full physical exam once a year. Your vet will check the heart, lungs, eyes, ears, teeth, skin, and weight. They’ll run a quick body condition score to flag early obesity. Senior dogs need to go twice a year, since conditions like kidney disease, diabetes, and arthritis can creep up fast.

Come prepared. Bring a list of questions, note any behavior changes, and bring records of past vaccines and medications. The more your vet knows, the better care your dog gets.

Arthritis

Arthritis is a common health problem in dogs and can cause significant pain and discomfort. 

Fortunately, there are many things that you can do to help your dog manage their arthritis and live a happy, healthy life.

The first step is to talk to your veterinarian about your dog’s arthritis. They can help you develop a treatment plan for your dog. This may include weight management, exercise, supplements, medication, or other therapies.

Weight management is essential for dogs with arthritis because excess weight can stress joints and worsen pain. Exercise is also crucial because it helps maintain joint flexibility and muscle strength. Supplements such as glucosamine and chondroitin sulfate can also help manage arthritis pain.

Medication may also be necessary to control pain and inflammation associated with arthritis. Your veterinarian can discuss the options with you and help you choose the best medicine for your dog.

There are many other things that you can do to help your dog with arthritis.

For example, providing them with a soft bedding area and avoiding hard floors can help make them more comfortable. You should also give them regular massages, toys, and chews specifically designed for dogs with arthritis.

Bloat

Bloat is a severe condition that can affect any dog, but it is most common in large or giant breeds. Itoccurs when the stomach fills with gas or food and twists on itself, cutting off the blood supply. If left untreated, bloat can be fatal.

There are several things pet owners can do to help prevent bloat:

• Feed your dog several small meals throughout the day instead of one large meal.
• Avoid giving your dog table scraps or other high-fat foods.
• Exercise your dog regularly to help keep its digestive system moving properly.
• If your dog is prone to bloat, talk to your veterinarian about preventive measures, such as a gastropexy (stomach-tieback) surgery.

Cancer

Cancer is one of the leading causes of death in dogs. While the exact cause of cancer is unknown, several risk factors include:

• Age: Cancer is most common in older dogs
• Breed: Certain breeds are more prone to cancer than others. For example, Golden Retrievers and Boxers have a higher incidence of lymphoma.
• Gender: Males are more likely to develop prostate cancer, while females are at greater risk for mammary tumors.
• Environment: Dogs exposed to secondhand smoke or other carcinogens may be more likely to develop cancer.

Many types of cancer can affect dogs, but some of the most common include lymphoma, mast cell tumors, osteosarcoma, and melanoma. Symptoms will vary depending on the type and location of the cancer, but may include weight loss, lethargy, difficulty breathing, and abnormal bleeding. 

If you notice any potential symptoms, contact your veterinarian right away for an evaluation.

Cancer can be a scary diagnosis, but with early detection and treatment, many dogs can go on to live long and happy lives.

Breed-specific considerations

Understanding your dog’s breed-specific health needs is essential for providing optimal care. Different breeds have evolved with distinct physical characteristics and genetic predispositions that can significantly impact their health requirements.

Brachycephalic breeds

Brachycephalic breeds, such as Bulldogs, Pugs, French Bulldogs, Boston Terriers, and Shih Tzus, have shortened skulls and flat faces that can cause significant breathing difficulties.

These breeds are prone to Brachycephalic Obstructive Airway Syndrome (BOAS), which can cause snoring, snorting, difficulty breathing, exercise intolerance, and overheating. The compressed airways make it harder for these dogs to regulate their body temperature through panting.

Large and giant breeds

Working and sporting breeds

Toy and small breeds

Herding breeds

Brachycephalic breeds with long backs

Brachycephalic breeds and swimming

Canine influenza

Canine influenza, also known as dog flu, is a contagious respiratory disease caused by specific Type A influenza viruses known to infect dogs.

Two main strains of the virus have been identified: H3N8 and H3N2. Canine influenza is most commonly spread through respiratory secretions and can be transmitted through barking, coughing, sneezing, and contact with contaminated surfaces and objects.

Symptoms of canine influenza can include coughing, sneezing, nasal discharge, fever, lethargy, and reduced appetite. In more severe cases, dogs can develop pneumonia, which can be life-threatening.

If you suspect your dog has canine influenza, it’s crucial to isolate them from other dogs and contact your veterinarian for guidance.

While most dogs recover from canine influenza with proper care and rest, some may require supportive care and medication to manage symptoms and prevent secondary infections.

Vaccination is available for both strains of the canine influenza virus, and it’s recommended for dogs at risk of exposure, such as those who frequently socialize with other dogs in settings like boarding facilities, dog parks, and grooming salons.

Preventive measures, such as practicing good hygiene, avoiding exposure to sick dogs, and keeping infected dogs isolated, can help reduce the spread of canine influenza.

If you have multiple dogs or frequently interact with other dogs, staying informed about local outbreaks and taking necessary precautions can significantly lower the risk of your dog contracting the virus.

Always consult your veterinarian for personalized advice on vaccination and preventive measures based on your dog’s needs and lifestyle.

CBD

This non-intoxicating cannabinoid found in cannabis has shown promise in various medical applications. CBD can provide numerous health benefits for humans and animals, from pain relief to anxiety reduction.

CBD oil for dogs is also easy to use and can be added to your pup’s food.

While more research is needed to understand CBD’s potential fully, studies show it can be a safe and effective treatment option for many conditions. 

If you’re considering using CBD to improve your dog’s health, here are a few things to keep in mind.

First, always start with a low dose and gradually increase as needed. Second, make sure you purchase CBD products specifically designed for pets. Third, always consult with your veterinarian before starting any new supplement routine.

Chronic conditions

Chronic conditions are diseases or disorders that last for a long time. They can be managed but not cured. 

Medication and lifestyle changes can control many chronic conditions.

Some of the more common ones include:

Arthritis: Arthritis causes joint pain and stiffness. It is common in dogs, especially older dogs. Many different treatments are available for arthritis, including medication, physical therapy, and weight management.

Cancer: Cancer is a disease in which cells grow out of control. It is one of the leading causes of death in dogs. Early detection and treatment are essential for increasing the chances of survival. There are many types of cancer, each with its own treatment options.

Diabetes: Diabetes is when the body does not produce enough insulin or cannot use insulin properly. Insulin is needed to regulate blood sugar levels. Dogs with diabetes require lifelong treatment with insulin injections or oral medications.

Kidney disease: It occurs when the kidneys cannot function properly. It can lead to kidney failure, which is fatal if not treated promptly. Treatment for kidney disease may include medication, special diets, and fluid therapy.

Coat and skin

A dog’s coat and skin are essential for their health. The fur helps protect the skin from the environment, while the skin helps regulate the body temperature. 

Healthy coat and skin are essential for a dog to stay warm in winter and cool in summer. 

There are a few things that you can do to help keep your dog’s coat and skin healthy:

Brush your dog regularly to help remove dead hair and dirt. This also helps stimulate blood circulation, which is good for the skin.

Give your dog regular baths with a mild dog shampoo. This will help remove any dirt, oil, and pollen build-up that could cause irritation or allergies.

Keep an eye on your dog’s nails and trim them regularly. Long nails can cause pain and damage to the nail bed.

Feed your dog a balanced diet with all the nutrients they need for healthy skin and fur. Omega-3 fatty acids are essential for maintaining healthy skin and coat.

Cushing’s Disease

Cushing’s disease is a common endocrine disorder in dogs that occurs when the body produces too much of the hormone cortisol. 

Cortisol is a stress hormone that helps regulate blood sugar levels, metabolism, and immune system function. While a small amount of cortisol is necessary for good health, excess cortisol can lead to various problems, including weight gain, muscle weakness, skin problems, and behavioral changes.

There are two types of Cushing’s disease: pituitary-dependent Cushing’s disease (PDH) and adrenal-dependent Cushing’s disease (ADH). 

PDH occurs when the pituitary gland, which regulates hormone production in the body, is dysfunctional. 

ADH occurs when there is a problem with the adrenal glands, which produce cortisol.

 In most cases, PDH is the more common form of Cushing’s disease in dogs.

Several potential causes of Cushing’s disease in dogs exist, but the exact cause is often unknown. Treatment typically involves medications to control cortisol production and manage symptoms. 

Most dogs with Cushing’s disease can live happy lives with proper treatment.

Dental care

According to the American Veterinary Dental Society, over 80% of dogs have some form of periodontal disease by the time they are three years old.

Good dental care is essential to keeping your dog healthy and can prevent other health problems.

Brushing your dog’s teeth is the best way to remove plaque and prevent periodontal disease, but it’s not always easy. 

Here are a few tips:

Use a soft-bristled toothbrush or fingerbrush explicitly designed for dogs for dental cleaning. 

Be gentle. Start slowly and increase your time brushing as your dog gets used to it.

Use pet-safe toothpaste (never use human toothpaste). Many flavors are available, so find one your dog likes.

If brushing isn’t possible or your dog already has periodontal disease, your veterinarian may offer other options, including professional cleanings, dental sealants, and oral rinses.

Dental disease

Here’s a sobering stat: by age three, about 80% of dogs already have some form of dental disease. It’s one of the most common health problems vets see, and one of the most overlooked by owners.

The culprit is plaque and tartar. Left unchecked, bacteria travel from the gums into the bloodstream and can damage the heart, kidneys, and liver. Bad breath is usually the first sign. Others include yellow or brown buildup on teeth, swollen or bleeding gums, trouble chewing, or dropping food.

Brush your dog’s teeth daily if you can. Use a toothbrush and toothpaste designed for dogs. Dental chews and crunchy kibble also help. Your vet may recommend professional cleanings. Don’t skip them.

Diabetes

Diabetes is a common disease in dogs and can be challenging to manage. However, your dog can live a long and healthy life with the right treatment plan.

There are two types of diabetes in dogs: Type 1 and Type 2. 

Type 1 diabetes is caused by the body not producing enough insulin, while type 2 diabetes is caused by the body not using insulin properly.

Symptoms of diabetes include increased thirst, increased urination, weight loss, and fatigue. If you notice any of these symptoms in your dog, take them to the vet for a checkup.

Checkups and treatment typically include insulin injections or oral medication. Your vet will work with you to create the best treatment plan for your dog.

With proper treatment, most dogs can live happy lives.

Diarrhea

As with all aspects of your dog’s health, it is essential to know the signs and symptoms of diarrhea and when to seek professional help.

Several things cause diarrhea, including dietary indiscretion, viral or bacterial infections, parasites, stress, or certain medications. Monitoring your dog’s stools for changes in frequency, consistency, or color is essential, as these can be signs of a more serious problem. 

If your dog has diarrhea, there are a few things you can do at home to help relieve their discomfort:

• Offer small, frequent meals of a bland diet.
• Avoid fatty or spicy foods.
• Make sure they have plenty of fresh water to drink.
• Add probiotics to their diet.
• Take them for short walks after each meal.

If your dog’s diarrhea persists for more than a day or two, shows signs of dehydration, or has any other accompanying symptoms such as vomiting or fever, consult your veterinarian. 

They will be able to determine the cause of the diarrhea and recommend the best treatment.

Ear infections

Ear infections are among the most common problems veterinarians see. Allergies, bacteria, mites, and more can cause them. 

The good news is that they’re often relatively easy to treat and prevent.

Here are a few things you should know about ear infections in dogs:

• Ear infections can be painful for your dog. If you notice your dog shaking his head or scratching at his ears, it’s time to see the vet.
• Allergies often trigger ear infections. If your dog is prone to allergies, talk to your vet about ways to reduce his exposure to potential triggers.
• Bacteria and yeast can also cause ear infections. Your vet can prescribe medication to clear up the condition and help prevent it from returning.
• Mites are another common cause of ear infections in dogs. These tiny parasites can be difficult to eliminate, but your vet can help you find the best treatment option for your dog.

If you think your dog may have an ear infection, don’t delay seeking veterinary care. With prompt treatment, most dogs will quickly recover and return to their usual selves.  

Emergency preparedness and first aid

Quick action saves lives. Keep a pet first-aid kit with gauze, adhesive tape, 3% hydrogen peroxide, a thermometer, tweezers, Benadryl, styptic powder, saline, and a muzzle. Store vet numbers and the ASPCA Poison Control number: (888) 426-4435.

Choking: Check the mouth for visible obstructions and remove carefully. Perform Heimlich if needed—upward thrusts below the rib cage. Seek vet care immediately.

Poisoning: Call vet or Poison Control immediately. Never induce vomiting unless instructed. If directed: 1 teaspoon hydrogen peroxide per 5 pounds (3 tablespoons max). Bring packaging to your vet.

Heatstroke: Dogs are highly susceptible to heatstroke because they cannot cool themselves as efficiently as humans.

Bleeding

Seizures

Fractures and broken bones

Exercise

The best way to keep your dog healthy is to make sure it gets plenty of exercise. A good rule of thumb is to ensure they get at least 30 minutes of moderate exercise daily. This can be a combination of walks, runs, and playtime. 

Talk to your vet if you need to figure out how much exercise your dog needs.

Exercise has many benefits for dogs. It helps them stay at a healthy weight, strengthens their muscles and bones, improves their cardiovascular health, and relieves stress. Exercise is also great for their mental health, providing positive stimulation and helping reduce boredom.

If you need to get used to exercising your dog regularly, start slowly and gradually increase the amount and intensity of the exercise. 

You don’t want to overdo it and risk injuring your dog or causing them undue stress. And always ensure they have plenty of water available when exercising.

Eye health

As your dog ages, it’s essential to monitor its eye health. Like humans, dogs can develop cataracts, glaucoma, and other age-related eye problems.

Here are some tips for keeping your dog’s eyes healthy:

• Have your vet check your dog’s eyes at least once a year. This is especially important if your dog is over 7.
• If you notice any changes in your dog’s eyes, such as cloudiness, redness, or discharge, take him to the vet immediately.
• Wipe your dog’s eyes with a damp cloth daily. You can also use a pet-safe eye wash to keep their eyes clean and irritation-free.
• Make sure your dog gets plenty of exercise and fresh air every day. This will help keep his overall health in tip-top shape, which, in turn, will help his eyes stay healthy.
• Feed your dog a balanced diet rich in antioxidants and omega-3 fatty acids. These nutrients support overall eye health and help prevent age-related eye problems.

Fleas and ticks

Fleas and ticks are parasites that can cause your dog several health problems, including skin irritation, allergies, and diseases. 

While several products are available to help control these pests, it’s essential to understand how to use them properly and what to do if your dog becomes infested.

The first step in preventing fleas and ticks is to ensure your dog is up to date on their vaccinations. 

This will help reduce the risk of diseases that these parasites can transmit. Several topical and oral products are available to repel or kill fleas and ticks. 

Follow the directions carefully when using any of these products, as they can be toxic if misused.

If your dog has started scratching more than usual or seems uncomfortable, immediately check them for fleas and ticks. 

These parasites can be difficult to spot, so it’s essential to conduct a thorough examination. If you find any fleas or ticks, remove them immediately with tweezers or a special flea or tick comb. You may also need to treat your dog with a product that kills fleas and ticks.

By taking simple precautions and recognizing the signs of an infestation, you can help keep your dog healthy and free from these pesky parasites.

Healthy diet

A healthy diet is one of the most important aspects of keeping your dog healthy. 

Like humans, dogs need a balanced diet to stay healthy and avoid disease. A good diet for a dog includes plenty of protein, fat, and carbohydrates, as well as essential vitamins and minerals.

 There are various ways to ensure your dog is getting a healthy diet. 

One option is to feed them commercial dog food formulated to meet their nutritional needs. 

Another option is making your dog food at home using fresh, whole ingredients.

Whichever route you choose, it’s essential to consult with your veterinarian to ensure your dog is getting all the nutrients they need for optimal health.

Heart disease

Heart disease is one of the leading causes of death in dogs. Several things, including genetics, diet, and lifestyle, can cause it. While there is no one-size-fits-all approach to preventing heart disease, some general guidelines can help keep your dog’s heart healthy.

Diet is an essential factor in maintaining heart health. Feeding your dog a balanced, nutritious diet can help reduce the risk of heart disease. Avoiding high-fat and high-sodium foods can also help keep your dog’s heart healthy.

Exercise is another critical factor in maintaining heart health. Regular exercise can help your dog strengthen its heart muscle and reduce the risk of heart disease.

If you think your dog may be at risk for heart disease, talk to your veterinarian about steps you can take to prevent it.

Heartworm

Heartworm is a severe and potentially fatal condition that affects dogs. Parasitic worms that live in the heart and lungs of infected animals cause the disease. These worms can grow up to 12 inches long and cause severe damage to the heart, lungs, and blood vessels.

The bite of infected mosquitoes transmits heartworm. When a mosquito bites an infected animal, it ingests microscopic larvae called microfilariae. These larvae mature into infective-stage worms inside the mosquito. When the mosquito bites a healthy dog, it injects the infective worms into the dog’s bloodstream.

Once inside the dog, the worms travel to the heart and begin to mature. The adult worms can live for 5-7 years in the heart and lungs of an infected animal, causing damage. If left untreated, heartworm disease can be fatal.

Heartworm disease is preventable with year-round monthly heartworm preventive medication. Several preventive medicines are available, so talk to your veterinarian about which suits your dog. If your dog is infected with heartworm, treatment options are available, but they are much more difficult (and expensive) than preventing the disease in the first place.

Hiccups

Hiccups are common in dogs and usually aren’t cause for concern. If your dog has a single hiccup, there’s no need to worry. However, prolonged or recurrent hiccups could indicate a more severe condition.

Prolonged or recurrent hiccups may indicate an underlying medical condition, such as gastrointestinal, respiratory, or neurological disease. 

If your dog has prolonged or recurrent hiccups, consult your veterinarian for further evaluation and treatment.

Holistic and alternative health approaches

Many dog owners explore complementary therapies alongside conventional care. Beyond CBD for pain and anxiety relief, several holistic options may benefit your dog under veterinary supervision.

Acupuncture: Thin needles are inserted at specific points to stimulate healing and relieve pain. Effective for arthritis, hip dysplasia, and post-surgical recovery.

Chiropractic care: Focuses on spinal alignment and joint mobility to help with musculoskeletal issues and improve range of motion. Seek certified animal chiropractors working with your vet.

Herbal supplements: Turmeric (inflammation), chamomile (calming), milk thistle (liver support), and ginger (digestion) are increasingly popular.

Not all herbs are safe for dogs, and some interact with medications—consult your vet first.

Aromatherapy: Diluted essential oils such as lavender and chamomile may help calm anxious dogs. Never apply undiluted oils to the skin or ingest them, as many are toxic. Vet approval required.

Massage therapy: Improves circulation, reduces muscle tension, and enhances mobility. Particularly beneficial for senior, athletic, or recovering dogs.

Hydrotherapy: Low-impact water exercise tends to joints while building strength. Excellent for arthritis, obesity, or orthopedic recovery.

Holistic approaches complement but never replace veterinary care.

Always consult your vet before starting any alternative therapies, especially if you have existing conditions or are taking medications. Work with certified practitioners and monitor for adverse reactions.

Integrative medicine, combining conventional and complementary approaches, often provides the best outcomes.

Intestinal parasites

Many different types of intestinal parasites can affect dogs. Some more common ones include roundworms, hookworms, whipworms, and tapeworms. These parasites can cause various problems, including weight loss, diarrhea, vomiting, and anemia. If not treated promptly, they can even be fatal.

Most puppies are born with roundworms, which they get from their mothers while in the womb. They can also pick up hookworms and whipworms from contaminated soil. Tapeworms are usually acquired by eating infected fleas or rodents.

Adult dogs can become infected with these parasites if they eat contaminated food or drink contaminated water. They can also pick them up from contact with contaminated soil or other animals.

The best way to prevent intestinal parasites is to have your dog regularly vaccinated against them and to practice good hygiene habits (such as keeping their environment clean and disinfected). 

If you suspect your dog may have intestinal parasites, take them to the vet for a checkup.

Joint dysplasia

Joint dysplasia means the joint didn’t form quite right. Hip dysplasia is the most common type. Elbow dysplasia is a close second. Some dogs have both. It’s a congenital condition, so dogs are born with the predisposition, but lifestyle and timing of neutering can make it better or worse.

Symptoms include limping, difficulty rising, stiffness after exercise, and reluctance to climb stairs. If left untreated, dysplasia leads to arthritis and chronic pain. Treatment ranges from weight management and controlled exercise to surgery in severe cases.

Large and giant breeds, including German Shepherds, Golden Retrievers, and Labrador Retrievers, carry the highest risk. Maintaining a lean weight and avoiding high-impact exercise during puppyhood can significantly reduce the odds.

Kidney health

The kidney’s main job is to filter the blood and remove waste products from the body. But they also play a role in maintaining fluid and electrolyte balance and producing hormones that help regulate blood pressure.

So, how can you tell if your dog’s kidneys are healthy?

Here are some signs to look for:

• They’re drinking and urinating normally.
• They’re not displaying any signs of discomfort or pain when urinating.
• Their gums are pink and moist.

If you notice any changes in your dog’s urinary habits or if it seems to be in pain when urinating, it’s essential to have it seen by a veterinarian immediately, as these could be signs of a kidney problem.

Liver health

Proper care can prevent several liver diseases in dogs. The liver is a vital organ that plays a key role in metabolism, detoxification, and nutrient absorption. 

When the liver is not functioning properly, your dog may experience symptoms such as lethargy, loss of appetite, vomiting, and diarrhea. Liver disease can be severe and even life-threatening, so it’s essential to recognize the signs and symptoms and seek veterinary care if you think your dog may be affected.

There are a few simple things you can do to keep your dog’s liver healthy:

• Feed a balanced diet: A nutritious diet is essential for all dogs, but critical for those with liver disease. Be sure to consult your veterinarian about your dog’s best diet.
• Avoid toxins: Many everyday household products can be toxic to dogs, so keep them out of reach. Some plants can also be poisonous to dogs, so research which ones to avoid before bringing them into your home.
• Regular exercise is vital for all dogs, but it can benefit those with liver disease. Regular exercise helps the liver by promoting blood flow and aiding in toxin removal.

Mental health

Mental health is an integral part of a dog’s overall health. Like humans, dogs can suffer from mental health problems like anxiety, depression, and post-traumatic stress disorder (PTSD). Various factors, including genetics, environment, and life experiences, can cause these conditions.

While mental health problems are often invisible, they can profoundly impact a dog’s quality of life. Dogs with mental health issues may seem withdrawn or uninterested in activities they once enjoyed. They may be more prone to aggression or other behavioral problems. In severe cases, dogs may even try to harm themselves.

If your dog suffers from a mental health problem, talk to your veterinarian to determine if an underlying medical condition causes the problem or is genuinely psychological. 

If it is determined that your dog has a mental health problem, there are treatments available that can help improve your dog’s quality of life.

ADHD: Attention Deficit Hyperactivity Disorder (ADHD) is a neurological disorder affecting humans and dogs. Dogs with ADHD may exhibit hyperactivity, impulsiveness, and inattentiveness. While there is no cure for ADHD, there are ways to manage the symptoms and help your dog.

Autism: Canine autism is a developmental disorder that affects a dog’s social skills and ability to communicate with other dogs and people. Dogs with autism may be withdrawn and unresponsive, or they may be excessively fearful or aggressive. There is no cure for canine autism, but there are ways to help your dog manage its condition and live a happy life. With the proper support, your dog can still enjoy all the joys of life, even if it doesn’t quite fit into the “normal” mold.

Canine Cognitive Dysfunction: Canine Cognitive Dysfunction (CCD) is a condition that affects a dog’s ability to think, remember, and learn. It is similar to Alzheimer’s disease in humans. CCD can impair a dog’s memory, attention span, and problem-solving ability. It can also cause changes in behavior, such as increased anxiety and confusion. The exact cause of CCD is unknown, but it is related to aging. There is no cure for CCD, but there are ways to manage the condition and help your dog.

Mental stimulation

Mental stimulation is vital to keeping your dog happy and healthy. Just as people do, dogs need mental stimulation to stay sharp. Without it, they can become bored, anxious, and even depressed.

There are many ways to provide mental stimulation for your dog. One of the best is through interactive toys and games. These can help your dog use its natural problem-solving abilities while providing much-needed exercise. Other great options include puzzle feeders, nose work games, and training classes.

Whatever route you choose, ensure you provide your dog with enough mental stimulation daily. A tired dog is a happy dog.

Muscle spasms

If your dog experiences muscle spasms, seek veterinary care immediately. Muscle spasms can be caused by various underlying health conditions, some of which may be serious.

Your veterinarian will likely perform a physical examination and order diagnostic tests to help determine the cause of your dog’s muscle spasms. Once the underlying cause is determined, treatment can begin. Muscle spasms may sometimes resolve on their own with no treatment necessary.

Nail and paw care

Nail and paw care are essential for keeping your dog healthy and comfortable. Here are some tips to help you navigate this important aspect of dog care:

• Keep your dog’s nails trimmed. Overgrown nails can be painful and uncomfortable for your dog, leading to health problems such as infections.
• When trimming your dog’s nails, be careful not to cut them too short. Cut only the tip of the nail, taking care not to cut into the quick (the blood vessel in the nail). If you accidentally cut into the quick, apply pressure to stop bleeding.
• Inspect your dog’s paws regularly. Check for any cuts, cracks, or other signs of injury or irritation.
• Keep your dog’s paw pads clean and free of dirt and debris. This will help prevent infection and keep your dog’s paws healthy.

These tips help ensure your dog’s nails and paws stay healthy and comfortable.

Neutering

Spaying and neutering do a lot of good. They prevent unwanted pregnancies, reduce the risk of certain cancers, and eliminate some behavioral headaches.

Neutered males are less likely to roam, mark territory, or fight. Spayed females avoid the heat cycle and the risk of a life-threatening uterine infection called pyometra.

But the question is, when to do it? That’s gotten a lot more nuanced in recent years.

The old rule vs. the new science

Dogs can be neutered as early as 8 weeks old, but most vets recommend waiting until they are between 6 and 9 months old. Some vets recommend waiting longer for larger breeds to develop properly before surgery. Spaying typically occurs at six to eight months.

For decades, the standard advice was simple: spay or neuter at six months. One rule. Every dog. But the science has moved on, and so has best practice.

Sex hormones aren’t just about reproduction. Estrogen and testosterone signal the growth plates in your dog’s bones, telling them when to stop growing.

Remove those hormones too early, and that signal never fully arrives. The growth plates stay open longer, the bones develop differently, and the joints can end up misaligned. In large breeds, that’s a recipe for hip dysplasia, elbow dysplasia, and cranial cruciate ligament tears down the road.

Current timing guidelines by size

Small and medium breeds (under 45 lbs): The traditional window of 6 to 9 months still holds. Growth plates close earlier in smaller dogs, so the risk to joint development is low.

Large and giant breeds (over 45 lbs): Vets now strongly recommend waiting until skeletal maturity, which means 12 to 18 months, sometimes longer, depending on the breed. A 2024 study from UC Davis School of Veterinary Medicine, published in Frontiers in Veterinary Science, analyzed data from 41 breeds and found that early neutering in large breeds significantly raised the risk of joint disorders and certain cancers. Golden Retrievers and German Shepherds showed among the highest risks associated with early procedures.

The AAHA Canine Life Stage Guidelines now reflect this shift. For large breeds, they recommend waiting until growth has stopped, typically between 9 and 15 months.

The cancer question

It’s not as simple as “later is always better.” Timing also affects cancer risk, and the relationship is complicated.

Spaying female dogs reduces the risk of mammary tumors and eliminates ovarian and uterine cancer. Neutering males prevents testicular cancer.

But early neutering in certain large breeds can actually raise the risk of other cancers, including lymphosarcoma, hemangiosarcoma, mast cell tumors, and osteosarcoma.

That’s why breed-specific guidance matters so much now. The AKC Canine Health Foundation has published easy-to-use tables with spay/neuter recommendations for 33-plus breeds. Your vet can help you navigate the right window for your dog’s specific situation.

Bottom line

Talk to your vet. The right timing depends on your dog’s breed, size, sex, lifestyle, and individual health.

There’s no universal answer anymore, and that’s actually a good thing. It means decisions can be tailored to your dog rather than applied by default.

The benefits of spaying and neutering still hold strong: population control, reduced health risks, and better behavior. The question is just when.

Obesity 

Over half of dogs in the United States are overweight or obese. That’s not a minor stat. Obesity shaves years off a dog’s life, and it raises the risk of diabetes, joint problems, heart disease, high blood pressure, and pancreatitis.

How do you know if your dog’s too heavy? Run your hands along their sides. You should be able to feel the ribs without pressing hard. If you can’t, it’s time to have a weight conversation with your vet. Dogs that are 15% over their ideal weight are considered overweight. Above that, they’re in obese territory.

The fix isn’t complicated, even if it isn’t easy. Measure food portions. Cut treats to no more than 10% of daily calories. Get moving. Regular walks help with weight, cardiovascular fitness, and mental health all at once.

There are many risks associated with obesity in dogs, including decreased lifespan, increased risk of developing diabetes and joint problems, and a decrease in quality of life.

Obesity is one of dogs’ most preventable health problems, yet it is still one of the most common. An estimated 40% of dogs in the United States are overweight or obese. Like humans, being overweight or obese puts dogs at risk for several serious health problems.

Some of the most common risks associated with obesity in dogs include:

• Shortened lifespan: One study found that obese dogs had a significantly shorter lifespan than healthy-weight dogs. The average lifespan of an obese dog was 2.5 years shorter than that of a healthy-weight dog.
• Increased risk of developing diabetes: Dogs that are overweight or obese are much more likely to develop diabetes than healthy-weight dogs. Obesity is the leading cause of diabetes in dogs.
• Joint problems: Obesity can strain your dog’s joints, leading to joint pain or arthritis. If your dog already has joint pain, carrying extra weight can worsen it.
• Decreased quality of life: Obesity can significantly impact your dog’s quality of life. Overweight and obese dogs are more likely to suffer from fatigue, heat intolerance, and difficulty breathing. They may also have trouble getting around and playing.

Pain management

There are various ways to manage dog pain, and the best approach depends on the individual dog and the cause of the pain. If your dog is in pain, you must talk to your veterinarian about how to manage it. They can help you create a plan that includes medical and non-medical treatments.

Medical treatments for pain management in dogs include medication, acupuncture, and laser therapy. Non-medical treatments include massage, physical therapy, and dietary or exercise changes. A combination of both medical and non-medical therapies is often the most effective.

The type of medication prescribed will depend on the severity of the pain and the underlying cause. Commonly used drugs include NSAIDs (such as ibuprofen or aspirin), opioids (such as codeine or tramadol), and gabapentin or carprofen.

Acupuncture

This traditional Chinese medicine technique involves inserting thin needles into specific points on the body. It is effective for managing pain in some dogs. 

Laser therapy

This therapy uses light energy to reduce inflammation and pain. 

Massage

Regular massages can help relax muscles and relieve tension, which can contribute to pain. 

Physical therapy

Focused exercises can help strengthen muscles and improve the range of motion, reducing pain. 

Changes in diet or exercise may be necessary if obesity or joint problems contribute to your dog’s pain.

Puppy proofing

Puppies are full of energy and love to chew on things, so it’s important to puppy-proof your home to prevent any accidents. Some tips for puppy-proofing your home include:

• Keep all cleaning products, chemicals, and medications out of reach.
• Put away any small objects that a puppy could choke on.
• Block off any areas of the home you don’t want your puppy to have access to.
• Provide your puppy with plenty of chew toys to keep them occupied.

Seasonal and environmental tips

Separation anxiety

Anxiety is a normal emotion we all feel at times, but it can be debilitating when it becomes excessive and persistent. Separation anxiety is one of the most common types of anxiety in dogs. It can be triggered by anything that causes your dog to feel separated from you, such as going to work, running errands, or even just taking a shower.

Symptoms of separation anxiety can include pacing, panting, whining, barking, chewing, or digging at furniture or doorways, having accidents indoors, and seeking constant attention from you. If your dog is exhibiting any of these behaviors, it’s vital to seek professional help from a veterinarian or certified animal behaviorist. 

With proper treatment, most dogs with separation anxiety can learn to cope with their fear and live happy lives.

Sleep

Dogs need about 12 to 14 hours of sleep daily, and puppies need even more. If your dog isn’t getting enough sleep, it can lead to problems like weight gain, anxiety, and depression.

There are a few things you can do to help your dog get the sleep it needs:

Ensure your dog has a comfortable bed in a quiet place where it won’t be disturbed.

Create a routine so your dog knows when it’s time to go to bed and when it’s time to wake up. This could include taking a final walk before bedtime and maintaining a consistent wake-up time.

If you’re concerned that your dog isn’t getting enough sleep, talk to your veterinarian. They can help you determine if there is a problem and offer solutions.

Sunscreen

Dogs are just as vulnerable to UV rays as humans, risking sunburn, skin rashes, allergies, and even skin cancer without protection.

Dogs with short or thin coats, light-colored fur or skin, pink noses, bald spots, or recent surgical areas are at higher risk, especially if they spend over 15 minutes outside or enjoy activities like the beach, hiking, or lounging by the pool.

Focus on applying sunscreen to areas with exposed or thin fur, such as the nose, ear tips, belly, groin, and any pink or bald patches.

Apply sunscreen thoroughly to these sensitive spots; a thin layer won’t suffice.

UV rays are a year-round threat, amplified by snow, altitude, and sunny or even cloudy days.

Use sunscreen any time your dog is outside for an extended period, reapplying every two hours, and don’t skip sun protection in spring, fall, winter, or overcast weather.

Supplements

Many supplements on the market claim to be helpful for dogs, but knowing which ones are effective can take time. 

Do your research before giving your dog any supplements, and talk to your veterinarian to see whether a particular supplement is right for your dog. 

Some supplements, including omega-3 fatty acids, joint supplements, probiotics, and vitamins, can benefit dogs.

Thyroid

The thyroid is a small, butterfly-shaped gland located in the neck. It produces two main hormones: thyroxine (T4) and triiodothyronine (T3). These hormones regulate metabolism, the process by which the body converts food into energy.

Thyroid problems are relatively common in dogs and can cause a range of symptoms. If your dog has any of the following symptoms, it could be indicative of a thyroid problem:

• Weight gain or loss
• Excessive drinking or urination
• Hair loss or thinning coat
• Hyperactivity or lethargy
• Increased appetite

If you suspect your dog may have a thyroid problem, bringing him to the vet for an evaluation is essential. Several tests can diagnose thyroid problems, and treatment is typically effective.

Vaccines

Vaccines are vital for keeping dogs healthy. They help protect against many diseases, including some that can be deadly. 

Many different types of vaccines are available for dogs, and your vet will recommend the ones that are best for your dog based on their age, health, lifestyle, and risk factors. Some dogs may need only core vaccines, while others may require additional vaccines depending on their exposure risk.

Core vaccines are recommended for all dogs, regardless of lifestyle or risk factors. They include vaccinations for rabies, distemper, hepatitis, and parvovirus. 

Non-core vaccines may include Bordetella (kennel cough), Lyme disease, leptospirosis, and others.

Vitamins

Several vitamins are essential for dogs, and they can be divided into two main categories: water-soluble and fat-soluble. 

Water-soluble vitamins include Vitamin C and the B-complex (thiamine, riboflavin, niacin, pantothenic acid, biotin, folic acid, and Vitamin B12). Fat-soluble vitamins include Vitamins A, D3, E, and K.

Most dogs get the majority of the vitamins they need from their diet. However, some dogs may require supplementation if they are not eating a well-balanced diet or have certain health conditions that impact their ability to absorb nutrients. 

For example, older dogs may need additional Vitamin C to support their immune system, and dogs with liver or kidney disease may require increased levels of specific B vitamins. Dogs with gastrointestinal issues or taking certain medications may also benefit from vitamin supplementation.

If you consider giving your dog a vitamin supplement, you must talk to your veterinarian first. They can help you determine if your dog is likely to benefit from supplements and recommend the best product for its needs.

Water

Water is essential for optimal dog health. It makes up about 60% of your dog’s body weight and plays a vital role in many of the body’s systems, including:

• Circulation: Water transports nutrients and oxygen to cells and removes waste products.
• Temperature regulation: Water helps maintain the body’s temperature.
• Digestion: Water aids in the digestion of food.
• Protection: Water lubricates joints and tissues, helping protect organs.

It is crucial to ensure your dog has access to clean, fresh water at all times. If you are unsure about the quality of tap water, consider using filtered or distilled water. 

You should also be aware of the signs of dehydration in dogs, which include excessive panting, lethargy, dry mouth, and sunken eyes. If you notice these signs, give your dog small sips of water until they recover.

Worms and parasites

Worms and parasites are common for dog owners, but panic is unnecessary. With some knowledge and simple precautions, you can keep your dog healthy and free of these pests.

Two main types of worms that can infect dogs are roundworms and tapeworms. 

Roundworms are the most common type of worm in dogs and can be transmitted to puppies through their mother’s milk or through contact with contaminated soil. 

Tapeworms are less common but can be contracted by dogs who eat infected fleas.

Most worms are not harmful to humans, but some types can cause serious illness in people, so it is vital to have your dog checked by a veterinarian if you suspect they may have worms. 

Treatment is usually simple and effective. Remember to follow your veterinarian’s advice on prevention and treatment to keep your dog healthy and happy.
