Tallest Dog Breeds: 15 Largest Dogs On The Planet

Whether you’re looking for a large dog to welcome into your home, or you’re just curious about which are the tallest dog breeds, we’ve prepared a list of the large dogs that exist today.

There are some rules when measuring dogs. The dog’s height is measured when the dog is standing on all of its four legs. We don’t consider the height from the top of the dog’s head to the ground, but the real height is considered from the ground to the shoulders also called withers.

Although a dog that has a long neck or a huge head may appear taller than the dog whose height is larger at the withers, he is not considered to be taller than the other.

We used the American Kennel Club’s (AKC) measurements as the standard average height for certain breeds. Although there is only one that holds the title of the tallest dog breed, there are a few others that are close to that standard height that deserve to be mentioned.

Can you imagine how tall these dogs are? We’re talking about 30 inches and over! Let’s take a look at the top 15 tallest dog breeds we picked out in no particular order for those of you who believe that size does matter!
