Do American Mastiffs require a lot of exercise?
American Mastiff puppies are as active as any other puppies, but are inclined to be lazy as adults. They will keep more fit and be happier if they are given regular exercise. Like all dogs, American Mastiffs should be taken on regular daily walks to help release mental and physical energy. It’s in a dog’s nature to walk. They should always be leashed for their protection while in public.
