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.

Caucasian Shepard

Like the Caucasian shepherd, this dog derives from Turkey, where it’s historically been used to herd farm animals. These pups are intelligent and independent and need an owner capable of training them and handling their dominant nature.

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.

“Newfies” were initially bred to help fishermen and are excellent swimmers.

A giant teddy bear, Newfoundland’s can reach an outstanding 150 pounds in weight.

French Mastiff

Used for protection, the Dogue de Bordeaux has also historically been a working dog that carries out tasks such as protecting farm animals. Known for their big heads, this breed needs a lot of exercise and time outdoors. However, once they’re inside, French mastiffs love their well-deserved beauty sleep.

English Mastiff

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.

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. An Akita was the star of a 2009 Richard Gere film about a dog that spent nearly a decade in a train station waiting for its owner’s return.


Otterhound dog playing in the backyard

They’re fantastic swimmers and have a particularly well-developed sense of smell. There are few members of this breed in existence, and it’s considered endangered.

The breed standard size for a bloodhound is 23 to 27 inches tall with a weight of up to 160 pounds. While these highly intelligent pups can be quite willful, their friendly nature makes them good family pets.
