What Qualifies as a Big Dog Breed?

Big is a fairly subjective word. It can mean the tallest when on all four paws, the tallest when standing on rear legs and stretching upwards, or the heaviest. Depending on which definition you’re considering, various breeds meet those requirements. In the list below, we have 20 giant breeds that are either tall, like the Great Dane, or very heavy, like the Mastiff breeds.

The 20 Largest Dog Breeds

1. Great Dane

  • Height: 35 Inches
  • Weight: 150 Pounds
  • Origin: Germany

The Great Dane is a giant dog, standing 35 inches tall. While they aren’t the heaviest canine, they can weigh up to 150 pounds, so owners will certainly know about it if the Great Dane wants to be a lap dog. Despite their mammoth size, the Great Dane is known for being affectionate and loving and is often described as a gentle giant. They’re especially gentle and calm around small children and smaller animals. However, that doesn’t change the fact that this dog will take up a lot of room in your home and your heart.


2. Saint Bernard

The Saint Bernard isn’t as tall as the Great Dane and is a few inches shorter. However, they weigh a little more. There are short-haired and long-haired Saint Bernards and both make excellent pets. Since they were initially raised to rescue lost travelers from snowy mountains, they’re friendly to strangers and comfortable in cold weather. Owners need to be prepared for heavy grooming if they have a long-haired Saint Bernard and a lot of drool, regardless of coat length.


3. Boerboel

The Boerboel is a docile breed that looks similar to a Mastiff. They were bred to protect livestock in South Africa. Although they appear quiet and peaceful, owners need to be prepared for a dog that can be territorial and may show signs of aggression. Early socialization and ongoing training are essential if you intend to take a Boerboel into your home. Even if your Boerboel is loving and calm, expect a lot of chewing, pulling, and heavy play sessions.


4. Tosa Inu
