Top 10 Largest Dog Breeds In The World

Mastiff (English)

Males average 78cm (31 inches), but the Kennel Club breed standard recognizes that they are typically taller and states that “size is desirable but only if combined with quality”. 

Irish Wolfhound

Captain Graham restored the Irish Wolfhound in the 19th century utilizing Scottish Deerhounds, Borzoi, Great Dane, and Pyrenean Mountain Dogs. Their history dates back to the 1st century A.D.

Saint Bernard

When you say "giant breed," most people think of the St. Bernard.  With a breed average height of 74 cm (but can be much taller) and a broad muscular physique, they are massive dogs. 

Newfoundland 

Newfoundlands, or ‘Newfies’, are another notable large breed that loves water. This obsession begins when pups try to get in their water dishes or tip them over to wallow in the puddle! 

Dogue de Bordeaux

The Dogue de Bordeaux, often known as the French Mastiff, is a large dog despite being smaller than the huge breeds. Known for their reddish fawn color and smiling, wrinkled face, this Molosser breed has a mixed ancestry! 

Leonberger 

Their reddish gold coat and beautiful black mask make the Leonberger one of the most gorgeous big breeds. The Leonberger was bred from St Bernards, Newfoundlands, and Pyreneans Mountain Dogs to resemble lions.

Anatolian Shepherd

This huge livestock guarding and droving breed has helped locals move cattle across the Central Anatolian Plateau and protect them from predators. 

Neapolitan Mastiff

The massive Neapolitan Mastiff is quiet and slow to react, but not stupid. They enjoy careful planning! They still think of themselves as lapdogs despite their heavy, flabby skin that wrinkles

Great Dane

Family-oriented, amusing, and even absurd (Scooby Doo was a Great Dane). However, they originated in Germany as boar hunting dogs that protected noble estates. 

Deerhound

Though not the smallest of the gigantic breeds, the Deerhound may be the lightest, standing at 76cm (29 inches) tall and weighing 42kg. Females are smaller and lighter than males.
