Just like people, dogs come in all shapes and sizes. There are some pups that can fit in the palm of your hand and some that can hardly fit in a car. No matter the size of your four-legged friend, you love them just the same as you would a dog of any other size.

When it comes to sizing for dogs, there are a few things you need to know in order to get started. Today we’re doing a deep dive on dogs of all sizes and how to make sure you understand how to properly measure them!

What Dog Sizes Mean

When looking to adopt a pooch, or looking to buy products for your four-legged friend, sometimes the sizing guides can become a little confusing. In most cases, however, you’ll have a guide similar to the guide made for people, with general sizes. The key to knowing what size your pet is is understanding what these sizes represent.

Small Dogs

When you think about a small dog, there’s a good chance you’re picturing a chihuahua. If that’s the case, you’d be spot on, as they’re one of the most popular small breeds available. Generally speaking, small dogs are anywhere from two to 22 pounds in weight, though the sizing of these dogs can be broken down a little bit further though.

  • Miniature dogs are on the smaller end of the small dog spectrum, weighing anywhere from three to 12 pounds, with two more distinctions able to be made.
  • Toy dogs weigh anywhere from five to 12 pounds.
  • Teacup dogs weigh four pounds or less.

Even though they’re small, these little pooches come with big personalities. Sometimes, this can lead to behavioral issues, as they can become quite aggressive towards other dogs or people if not socialized correctly.

Many small dogs also have health issues, mostly due to breeding issues. As these breeds are made to be smaller and smaller, they inherit issues in bloodlines, and purebred small dogs are almost certain to have health issues.

The height of a small dog can range anywhere from six to 18 inches, though they can be smaller or larger than this.

Popular examples of small dog breeds are:

  • Beagle
  • Chihuahua
  • Cocker Spaniel
  • Pomeranian

Medium Dogs

Medium dogs are the in-between size, and they tend to be what most people want out of a pup, even if they don’t know it. Medium dogs tend to have just enough energy, not too active or too lethargic. They don’t get too big, meaning that they’re manageable, and they don’t stay so small that they can’t keep up with you when outdoors.

Medium dogs tend to weigh anywhere from 23 to 57 pounds and stand anywhere from 18 to 25 inches at the shoulder, though depending on the breed, the height of the head can be much higher. This is considered the sweet spot for most people.

This is the largest grouping of dog breeds, and as such, the health problems that can be encountered are varied. Some breeds have respiratory issues, like bulldogs, while others end up having hip problems. 

It’s also important to mention that the medium grouping of dogs contains the largest number of working dogs available. These breeds are commonly seen as support dogs or other forms of service dogs. 

These are some of the most popular medium dog breeds:

  • Australian Shepherd
  • Bulldog
  • Border Collie
  • Dalmatian

Large Dogs

These pups are starting to get big! Large dogs are big enough to do some damage, though they don’t know it. Most times, these pups think that they’re lap dogs and that they belong on the couch with their best friend.

Large dogs can weigh anywhere from 58 to 99 pounds and can stand 30 inches tall at the shoulder. These dogs are large and in charge, as the name implies. It’s important to remember, though, that just like all the other sizes of dogs, they can be all shapes. Some are slender, while others are thick and muscular.

Behaviorally, it’s safe to say that most large dogs are friendly and have an overzealous nature when trying to make new friends. Because of this, they make good working dogs. If trained well, they make great guard dogs, as their size can be intimidating.

Physically, large dogs are prone to joint issues, specifically having to do with their hips and spine. These pups need regular checkups to keep everything aligned the way it should be.

Some popular large dog breeds are:

  • Boxer
  • German Shepherd
  • Golden Retriever
  • Malamute

Giant Dogs

Yep, they get bigger than the large breeds. These are your big pups, the ones that need an entire bed of their own. These pups are highly friendly and also highly protective. They’re absolutely massive and can even dwarf large breeds.

Giant dogs weigh 100 to 200 pounds and can be well over 30 inches in height at the shoulder when seated. When on their hind legs, they make most full-grown men look small. Most of these dogs are bulky rather than tall, though.

These dogs can be energetic and don’t know their own strength. If not trained well, they’ll be taking you for a walk rather than you taking them for one. This strength can lead to accidents with smaller folks and kids, but generally, the demeanor of giant dogs is friendly.

In terms of physical health issues, giant dogs suffer from musculoskeletal issues, as well as inherited issues due to breeding, just like with small dogs. It is important to keep this in mind when looking to adopt a giant dog.

Some good examples of giant dogs are as follows:

  • Great Dane
  • Newfoundland
  • Tibetan Mastiff
  • Saint Bernard

Do Doggie Sizing Guides Match Up

In most cases, you’ll find that plenty of dog sizing guides are similar and break down exactly what their sizes mean. If you’re having any doubts about the product, or your pup’s size, here’s how to measure your four-legged friend:

  • Top Line Back - Measure from where your dog’s neck meets their shoulders back to the base of their tail.
  • Neck Girth - Using a soft measuring tape, measure the thickest part of your pet’s neck, normally where it meets the shoulders.
  • Chest Girth - With that same soft measuring tape, measure the thickest part of your pet’s chest, normally just behind the front legs.

Knowing these three measurements can help you when looking to purchase new accessories for your pet, especially when shopping online.

Measure for Measure

When it comes to dogs, there are all shapes and sizes out there, but generally, we can categorize them into four groups. These four groups are small, medium, large, and giant. When thinking about these groups, it’s important to remember that the closer you are to either end of the spectrum, the more health problems you risk.

If you need to know your dog’s specific measurements, be sure to measure their top line back, as well as their neck and chest girth. These measurements will allow you to purchase any products with a size listed.
