The Bullmastiff is one of the most popular dog breeds. In this guide we cover its origin, temperament, care and the conditions it is most prone to, to help you look after its health.
Origin and history of the Bullmastiff
It was created in England in the 19th century by crossing the English Mastiff with the old Bulldog (in a 60/40 proportion) to help gamekeepers stop poachers without seriously injuring them. It is a powerful, calm guardian, deeply attached to its family.

Care and feeding
The Bullmastiff needs a balanced canine diet suited to its size and age, with weight control and fresh water always available. Look after its dental hygiene, brushing according to its coat, nails and ears, and keep up with vaccinations and deworming. Regular veterinary check-ups are key to catching any problem early.
Exercise and stimulation
The Bullmastiff needs daily walks and exercise to match its energy, plus mental stimulation through games, obedience or interactive toys. A dog that moves and «thinks» every day is a more balanced dog: the right exercise prevents boredom, stress and excess weight.
