Some people prefer small dogs, while others prefer big dogs. But like Goldilocks, sometimes you’ll find your best fit in the middle. Mid-size dog breeds are as energetic as small dogs and just as loving as big dogs.
Medium-size dogs typically weigh 30 to 70 pounds. They vary in activity level, temperament, and trainability.
There are definite advantages to choosing a mid-size dog.
Medium dogs don’t eat as much as large dogs and aren’t as fragile as small dog breeds. And they make great companions for active families.
But before you choose a dog, make sure you do your homework first.
You can start by considering this list of popular, fun-loving, medium dog breeds.

If you take your Am Staff on regular walks, they will naturally wear down their nails. However, you may still need to trim them occasionally.
Common Am Staff health problems include atopic dermatitis, hip dysplasia, and hypothyroidism.
