The American Kennel Club recognizes the Great Dane as the world’s tallest breed. These lovable giants originate from Germany. Great Danes usually reach around 28-30 inches tall and weigh between 100 and 120 pounds. However, a Great Dane called Zeus reached an impressive 44 inches tall and was included in the Guinness World Records as the tallest dog in recorded history. A natural protector, the Great Dane is a loyal companion that gets strongly attached to its owner and makes a perfect guard dog.

Saint Bernard

Saint Bernard is one of the most recognizable giant breeds out there, partly thanks to the popularity of the 1992 movie “Beethoven” and its sequel. Just like in the movie, members of this giant dog breed are perfect for family life due to their protective and affectionate nature. Initially, they were bred and trained by monks as rescue dogs to save hikers lost on the trails of the Swiss Alps. These mountain dogs reach a height of up to 30 inches and weigh between 120 and 180 pounds.

Newfoundland

A mix between Saint Bernard and rottweiler breeds, these majestic-looking pups are descendants of the Roman war dogs that served Julius Cesar himself. These dogs are very intelligent, loyal and fiercely protective. They do well in cold weather and can make ideal pets with early socialization. The American Kennel Club only recognized Swissies in 1955.

Akita

In Japan, Akitas are considered family protectors and symbols of health and happiness. These stunning dogs develop strong bonds with their humans but can be prone to dog aggression, which is why early training and socialization are an important part of owning a member of this ancient Japanese breed.

Otterhound
