Medium Sized Dog & Puppy Breeds


Note: While the breeds in this collection tend to be medium sized dogs, individual pets will vary.  Please consult the adoption organization for details on a specific pet.

Families choose to adopt medium dog breeds for many reasons. At the top of the list of why mid-sized dog breeds are a great choice is that there is a huge selection of pups since they are defined by weight, height and length – not just their size.

Medium dogs weigh between 20 and 60 pounds. Their height ranges between eight inches and 27 inches. Mid-sized, with all the charms of a dog of any size, this category of dogs can be from a medium small breed range like a Dachshund, Corgi and French Bulldog; a medium dog group such as a Beagle, Border Collie or Bull Terrier; or medium to large dog breed category like an Airedale Terrier, Samoyed or Chinese Shar-Pei.

While weight and size is an important factor in choosing an adoptable pet, there are a few more considerations to explore before you bring your new best friend home.


1. Size

Medium dogs range in size from a standard Dachshund to a Dalmatian. To determine the best size medium dog for you, consider whether you’d be able to lift and carry your pet if need be.

Another consideration for size is if there are younger children in the household. Matching the size of your medium dog puppy or adult to the smallest member of your family could mean fewer instances of children or pups being hurt or knocked over during playtime.


2. Temperament

A dog’s attitude can be a deciding factor in your adoption too. Are you interested in a pup that’s affectionate, alert, friendly, gentle, lively, playful, protective, docile or maybe quiet? Medium dogs, just like their range in sizes, have just as wide of a range of attitudes.

For example, Whippets are known for being sensitive. A large, rambunctious family can make a Whippet anxious. Wire Fox Terriers thrive on attention and the friendliness of children so these dogs are known to automatically want to jump into any and all activities with them.

The best way to measure temperament is to spend time with a dog and assess how he will integrate naturally into the varying energy levels and personalities of your family.


3. Energy

The energy of a dog is closely related to his activity level. It’s important to assess how much time you can dedicate to exercise your new best friend, and how often you’re able to ensure your medium-sized dog’s energy levels are satisfied. A good way to choose a dog that suits your activity is to match him to the lowest energy level amongst your pack – that would include human as well as any other dogs in your family.


4. Grooming

All dogs need some maintenance, and there are medium dogs that may need less or more of it depending on a few things. When it comes to coat and nail care, remember that longer coats may need regular grooming including washing and/or a blow-out. Other medium dogs require little or no coat maintenance except a nail trim every few weeks.

Keep in mind that there are medium dogs that may also have a coat that sheds, sometimes they have two coats which may mean more cleaning up and grooming than you’re used to. Before welcoming your new pup home, take some time to think about whether you have space in your week to bath, brush and blow-dry your best friend, or whether you’re able to support his grooming needs through regular visits to a dog day spa.
