His method of attack is to knock down an intruder and hold him on the ground. Unfortunately, because of his size, he can accidently knock down a child or an adult when he is playing.

Bull Mastiff Activity Level

How Active is the Breed?

Bullmastiffs tend to be lazy and will not expend any more energy than absolutely necessary. Therefore, they need to be taken on daily long walks and encouraged to exercise. Otherwise, they will put on weight.

They cannot tolerate extremes of temperature.

They are fairly inactive indoors, so they can live in an apartment setting.

How Much Exercise Does the Dog Need at every stage of its Life?

A small fenced yard for playing and walks will suit the needs of a young Bullmastiff. As he gets older, he will have to be encouraged to take walks and to play.


The short, rough coat of the Bullmastiff needs some brushing, but seldom needs bathing. Because the dog carries a lot of weight, check his feet often and keep the nails short.
