The Mastiff is a gentle giant among dog breeds. These massive, muscular dogs are known for their noble and loyal dispositions, making them ideal family pets.

One of the oldest dog breeds, these massive, heavy-boned dogs have been used as war, guard, and fighting dogs throughout the ages. They traced their roots back to ancient civilizations in Egypt and Rome and were used for guard duty and fighting. 

Although most now are family pets, they still take their role as protectors seriously. Mastiffs lack aggression and are well-mannered, meaning they can do well in most homes.

While they don’t require much space, extra room is always appreciated (mainly because of those long tails).

Like other large dog breeds, the dogs have shorter lifespans, but proper care can help them enjoy a healthy life.

Meet 11 Mastiff dog breeds and decide if you want to bring one home today.

Physical traits

Contents

Mastiffs are one of the heaviest dog breeds. They typically weigh over 200 pounds and stand at least 30 inches tall at the shoulder. Males can even outweigh some full-grown men! 

This canine giant has a rectangular-shaped body that is deep and thickly muscled. Their short double coats come in colors such as fawn, apricot, or brindle stripes. 

An adult mastiff’s head is comprehensive and massive, which gives them a unique appearance. The wrinkles on a mastiff’s face contribute to its wise and alert expression. 

Although mastiff puppies are energetic, older members of this breed tend to become more lethargic. That is why it’s essential to give them a moderate amount of exercise every day.

Mastiffs also tend to chew, drool, and snore — so be prepared if you’re considering adding one of these dogs to your family.

Temperament 

Although the dogs may look imposing, they are gentle by nature.

With proper socialization and training, they make great companions and loyal protectors.

Formal training classes may bore them quickly, so it’s essential to keep things fun and interesting.

Mastiffs communicate best with their eyes, so maintain eye contact when working with them.

The dogs bond with family members and tend to suffer from separation anxiety.

Grooming needs

This gentle dog breed needs bathing every six to eight weeks, depending on activity level and lifestyle.

With this short and dense coat, regular bathing is essential to minimizing shedding and maintaining healthy skin and coat. 

Be sure to pay attention to your dog’s face folds or wrinkles. Those wrinkles can trap dirt, dust, saliva, and debris, irritating sensitive skin.

Because skin folds are often moist, they provide the perfect environment for developing pyoderma, a bacterial infection.

Health issues

Like other large dog breeds, Mastiffs are prone to joint and heart problems. They also can suffer from bloat, a life-threatening condition when the stomach distends and twists.

These issues include seasonal allergies, eye anomalies, cancer, hip dysplasia, von Willebrand’s disease, degenerative myelopathy, and epilepsy.

These large dogs also tend to develop hygromas, swelling that protects the elbow joints. Talk with your vet to monitor hygromas to ensure they don’t become too large or get infected. If they do, you may need to treat them with antibiotics or have them drained or removed.

These big dogs don’t need much exercise and can stay physically and mentally healthy with free play and one- to two-mile daily walks. Be warned, the dogs are known for flopping down during walks when tired or overheated.

Watch Mastiff puppies and young adults to ensure they don’t get too rowdy and hurt themselves. Don’t let them run up and down stairs, jump from heights, or go on long walks.

Proper nutrition is critical to ensure your Mastiff experiences slow and steady growth.

Feed your dog a densely caloric diet with an appropriate calcium/phosphorous ratio to protect its bones and prevent skeletal disorders. Feed your dog at set times rather than allow free feeding, which can cause excessive weight gain.

The Great Dane is most easily recognizable by its large size. Males range from 32 to 34 inches tall and weigh anywhere from 120 to 200 pounds. Females are typically smaller, with a maximum height of 32 inches and weighing up to 130 pounds.

Great Danes come in various colors, from black and gray to harlequin (large black patches on a white coat) and merle (a dappled gray). The Harlequin variety is often confused with Dalmatians.

Despite their size and hunting dog history, Great Danes are relaxed and easygoing. They require daily exercise and plenty of space.

So, if you’re considering adopting one as a pet, ensure you have enough room to accommodate their stature.

Great Danes are not known for being excessive barkers but will alert you if they sense something amiss.

Extra companionship and close supervision are necessary to keep youngsters from getting bored and destructive.

Final thoughts on Mastiffs

The Mastiff is a classic guardian breed — big, powerful, and loyal. The dogs are good-natured and enjoy spending time with their people.

But potential owners should be aware that they require more care than other breeds.

Although they are gentle giants by nature, Mastiffs take their role as protectors seriously. They make great homebodies and get along well with other animals and children but require extra space to roam. 

Like other large breeds, these dogs have shorter lifespans than smaller dogs. However, your Mastiff can enjoy a full and healthy life with proper care.

If you’re considering a Mastiff breed for your family and you’ve done your research, start looking for a responsible breeder or rescue organization.
