Some people just adore little dogs that they can carry around. Others love majestic giant dog breeds best. What if your tastes lie somewhere in the middle? You might be a fan of medium-sized dogs. Neither too big nor too small, they are what many consider just right. These versatile dogs usually possess some traits of both small and large dogs.
What Size Is Medium?
What defines a medium-sized dog? It depends on who you ask. Small dog breeds tend to go up to about 20 pounds. Large dog breeds begin around 60 pounds. Some organizations break down dog sizes into detailed groups (e.g., extra-small, small, small-medium, medium, medium-large, large, extra-large, and giant). To keep it simple, let's look at popular breeds that fall between small and large. These breeds will range in average size from about 25 to 55 pounds.
Because of this wide weight range, medium-sized dogs make up a large portion of the dog breeds out there. Those who prefer medium-sized dogs love that they are small enough to fit in smaller spaces but large enough to play like a big dog.
There are also some potential advantages to having a medium-sized dog. They are not underfoot and fragile like some small dogs. Yet they often have longer lifespans and fewer orthopedic issues than large dogs.
No two dogs are exactly the same. A dog's breed should not be the only deciding factor when choosing a dog. While the breed can give you a general idea of what to expect, it's also important to consider the individual dog's personality, temperament, energy level, and trainability.
Have you got your heart set on a medium-sized dog? Fortunately, there are a great number of popular and beloved medium-sized dog breeds to choose from.

Before you look for a specific dog breed, consider adopting a mixed-breed dog. Each mutt is a one-of-a-kind dog. Mixed-breed dogs come in all sizes, especially medium. In many cases, mixed-breed dogs are healthy, smart, and friendly. By adopting a mutt, you would be providing a home for a dog that might otherwise end up euthanized due to pet overpopulation.
You can find the right mixed-breed dog for you by visiting local animal shelters and pet rescue groups. Shelter/rescue workers can often give you a general idea of the dog's personality and needs. Once you meet the dog, you can get a sense of these traits as well. However, a dog may act differently in the shelter than in a home. Consider choosing an organization that has a fostering program so you can find out more about the dog's behavior in a home environment. Talk to foster owners about each dog's personality, temperament, energy level, and trainability.

American Staffordshire Terrier
The American Staffordshire Terrier, or Am Staff is very similar to the American Pit Bull Terrier and is often casually called a pit bull. Unfortunately, pit bull-type dogs are often very misunderstood and considered dangerous. Some jurisdictions have legislation banning American Staffordshire Terriers and any dogs that resemble pit bulls.
Am Staffs have a quite large weight range. Averaging between 40 and 70 pounds, they are definitely on the larger size of the medium range. This is especially due to their muscular bodies. However, many Am Staffs fall in the lower part of the weight range, especially females. Also, it is often easy to find dogs mixed with pit bull-type dogs in a smaller size.
In general, the Am Staff is a highly affectionate and energetic dog that makes a wonderful companion for active households.
