What Size Dog Should I Get? A Quiz for Prospective Pet Owners!

By: Brianna Gunter

A group of dogs of different sizes sit together.

Congratulations on deciding that puppy parenthood is for you! Now that you’ve made the pivotal choice to bring a dog into your life, it’s time to decide what size is the right for you. Doggy dimensions vary wildly, but they can generally be grouped into small, medium, and large.

Believe it or not, the dog size decision could actually be more important than breed, gender, or color. After all, you can always learn to live with a pooch that is more outgoing and energetic than anticipated, or one who’d rather snooze all day than play a game of fetch. But if your pal grows to Clifford-sized proportions in your studio apartment, you’ll have to make some major living arrangement changes or worse, give up your pet.

Understanding different dog sizes

When people refer to dog sizes, they’re typically referring to weight. Because of this, some breeds may even fall into multiple size categories. Greater canine weights tend to come with taller statures, but this isn’t always the case.

For example, a Welsh corgi may not be all that taller than some toy breeds, but the corgi’s much bigger weight (and overall build) typically puts it in medium dog size territory rather than small. Here’s a quick rundown:

Small dogs

“Small dogs” typically refers to pups that weigh around 20 lbs. or less. Subcategories of small dogs include toy, miniature, and teacup breeds, though some breeds may fall into multiple of these classifications.

These adorable little canines are beloved around the world for their compact sizes and playful energy! However, there’s a common misconception that their small proportions mean less work for pet owners. In reality, small dog breeds still need plenty of exercise and snuggles with their humans—if their needs aren’t met, these rambunctious cuties can start behaving poorly.

Medium dogs

For those who prefer the personalities of bigger dogs but have limited space, a medium dog can be the way to go. These in-between pups can range from around 20 lbs. to 60 lbs. in weight, and they’re often playful and friendly without being too hyperactive. Many herding breeds fall into the medium dog range, serving as highly trainable and tolerant family pets—even if they get a bit stubborn at times.

Large dogs

At around 60 lbs. full grown or more, large dogs are at the tippy top of the size chart. “Giant” dog breeds (like the Great Dane or Irish wolfhound) are also included in this category, even though they may tower over other big dogs like the Labrador retriever.

Big dogs can have big personalities or be gentle giants, but all require more daily activity than smaller pups. In addition to considering their higher exercise and food needs, it’s important to research big breeds you’re interested in ahead of time before committing to these majestic creatures.

Ready to find out which dog size is for you? Go ahead and add up how many of each letter you wrote down.

Mostly As: A big dog seems like the right choice for you! Do your research on large dog breeds, and try talking to a local veterinarian about their exercise and nutrition needs. A big dog is a lot of commitment, but the right one will be a loyal companion whether you’re adventuring outdoors or snuggling on the couch. (Just make sure that couch is sturdy!)

Mostly Bs: Congratulations! You may be a great candidate for the best of both worlds, a.k.a. the beloved medium dog. Don’t just snag the first of these canines that you see though—they may seem like laid back pals, but all dogs are still a big responsibility. Try talking to a veterinarian near you to learn more about caring for a medium size dog before you select your new best friend.

Mostly Cs: You’re a special kind of person looking for a special kind of pet, and that may just be a small dog! These cute canines will quickly capture your heart with their congeniality and love of lap time, but be prepared for their high energy and chattiness. Reach out to a local veterinarian to make sure you have everything you need for a new little pal in your life.

Mostly Ds: You’re not quite sure what kind of dog would be the right fit, and maybe you’re not yet sold on the idea of being a puppy parent in general. That’s okay! Welcoming a dog of any size into your life is a major commitment that should be taken seriously. Try volunteering at a local animal shelter or do some pet sitting to get to know these wonderful creatures better and see if caring for a canine is a task you’re up for.

Size is just one indicator of dog personality

No matter what size dog you feel is the right choice, it’s important to keep an open mind. While common patterns are seen among different breeds and sizes, dogs are still individuals at the end of the day. Just because you have one Chihuahua who likes to run around and be vocal does not mean your next one won’t like to snooze quietly all day.

Adopting a dog is a big decision even for experienced pet parents. In addition to having to take lifestyle and personality into consideration, you’ll also have to make a plan for keeping your new pet healthy. Enrolling in dog insurance early on can help ensure your pal is protected throughout his life.
