16 Types of Giant Dog Breeds (With Pictures)

While some people prefer small dogs, there are some of us who adore giant dog breeds as well. Giant dogs have a reputation for being the most recognizable and hardest-working breed of dogs in the world today. However, giant dog breeds usually have a strong working instinct and a strong prey drive, meaning they can be quite a bit to handle and aren’t for everyone.

While giant dog breeds come with their negatives, there are also a ton of pluses for keeping one as a pet. Also, there are quite a few factors you’ll want to consider before choosing a giant dog as a family pet. We’ll give you 16 giant dog breeds and a bit of information about them so that you can make an informed decision on whether a giant breed of dog is the right choice for you and your lifestyle.

Height 28 to 32 inches
Weight 110 to 175 pounds
Life Expectancy 6 to 8 years

This majestic breed of dog actually more resembles a small horse than a dog, but don’t let its size fool you. The Great Dane is an easy-going dog that takes to apartment living well despite its size. These dogs were bred to hunt wild boars and to guard property and their families. They still make great guard dogs but are even-tempered and lovable for the most part.

Very friendly and outgoing, the only problem with the Great Dane is its short life span, which is only 6 to 8 years, meaning you might not get to spend as much time with your loyal friend as you would like.

  • Good for apartment living
  • Short lifespan
