Mastiff
Also known as: English Mastiff, Old English Mastiff
One of the largest dog breeds by mass - a gentle, dignified English guardian that is calm, good-natured and deeply affectionate with its family. Quietly loyal and patient, the Mastiff combines a courageous heart with a steady, trustworthy temperament that makes it a remarkable companion.
Origin and purpose
The Mastiff is an ancient British type, used over millennia as a war dog, estate guardian and (less creditably) in blood sports, before being refined into the modern show breed in the 19th century. It was bred above all to be a massive, intimidating but steady guardian.
Temperament
Kennel authorities describe the Mastiff as dignified, good-natured, calm and courageous — devoted to its family and naturally protective without being aggressive when well-raised. It is sensitive and responds best to gentle, consistent training. Its size demands early manners training while it is still liftable. Individual temperament varies more than the breed label suggests (Morrill et al., Science 2022).
Health and longevity
As a giant breed the Mastiff is typically short-lived. Controlled growth, lean weight and breeders who health-test are essential.
