The Mastiff is an ancient breed and one of the oldest in the world. Their early ancestor, known as the molossus, dates back as far as 3000 BC, but the modern Mastiff is quite different than their ferocious forefathers. Today, the Mastiff is a great family dog with a gentle and affectionate disposition. They tend to drool a lot, but that shouldn’t stop you from a wonderful life with these fine companions. These dogs can grow to be enormous animals – one Mastiff from England tipped the scales at 343 pounds!

Working Group dogs have been invaluable assets to man throughout the ages. The Doberman Pinscher, Siberian Husky and Great Dane are included in this Group, to name just a few. Quick to learn, these intelligent, capable animals make solid companions. Their considerable dimensions and strength alone, however, make many working dogs unsuitable as pets for average families. And again, by virtue of their size alone, these dogs must be properly trained.
Mastiffs have a giant body with a big square head. They are usually a bit longer than they are tall. Their distinguishing features are their giant size, massive head, and their mask of black fur around the face and head. Mastiffs are strong and powerful dogs, generally outweighing other taller breeds like the Great Dane and Wolfhound.
The AKC recognizes three standard colors for the English Mastiff: apricot, brindle, and fawn. The black mask is a standard marking for competition. Their fur is generally short and lies close to the body, but there are rare Mastiffs known as “fluffies” that grow longer hair.

Caring for a Mastiff means providing structured training, portion-controlled nutrition and moderate daily exercise to support their large frame. With early socialization, routine grooming and preventive veterinary care, these gentle giants can thrive as devoted family companions.

Origin: United Kingdom
Mastiffs have their roots in ancient times. Images of Mastiff-like dogs appear in bas-reliefs and figurines as far back as Assyria (6th century BC) and even early. One of the ancient breeding programs for the modern Mastiff occurred in Britain before the Roman Conquests.
The British continued to breed Mastiffs as working dogs and watchdogs throughout modern history. Formalized breeding started in the 1800s, and the Mastiff saw military service in the First World War. Breeding success in the UK took a hit during the rationing of the Second World War, but the Mastiff remains a popular dog around the world.
In America, a Mastiff club formed in 1879 but disbanded around the turn of the century. In that time, the Mastiff won official recognition by the AKC in 1885. The club reopened later in 1920 and the current Mastiff Club of America began in 1929. The Mastiff is in the top thirty most popular breeds in the United States today.
