Breed History:

The French Mastiff, known as the Dogue de Bordeaux, is one of the most ancient dog breeds in France, with roots dating back to at least the 14th century. Bred in the Bordeaux region, this powerful Molosser-type dog was traditionally used for guarding estates, pulling carts, and even hunting large game such as boars. Over time, it gained a reputation as a fearless guardian, loyal to its master and protective of its territory.

The breed’s popularity waned and resurged several times, especially after near-extinction during World War II. It gained international fame after appearing in the 1989 film Turner & Hooch, where a Dogue de Bordeaux starred alongside Tom Hanks, introducing the breed to global audiences.

Training:

The French Mastiff is intelligent but can be independent and stubborn.

Like many large breeds, the Dogue de Bordeaux is prone to certain health conditions, most notably:

• Hip and elbow dysplasia

• Heart problems, such as aortic stenosis

• Bloat (gastric torsion)

• Skin infections in facial wrinkles

Due to its large size, joint and cardiac health should be monitored closely with regular vet visits. Maintaining a healthy weight and eating in smaller, frequent meals helps reduce the risk of bloat. Owners should also clean skin folds regularly to prevent irritation and infection.
