Bull Mastweiler History
The Bullmastiff is a type of mastiff, a medium to large-sized working dog that was originally developed in the United Kingdom. Originally, the Bullmastiff was used as a guardian and as a protector of livestock. Because of its large size, strength and courage, the Bullmastiff was also used for bullbaiting, a sport in which bulls were baited or provoked into aggression by dogs and were then taunted and fought for sport. The modern-day Bulldog is descended from Old English Bulldogs, which were heavier and larger than the modern English Bulldog. The Bullmastiff was one of the earliest types of bulldog and its name derives from “Mastin”, a slang term for “Masculine”. The modern-day pure-bred English Bulldog is actually a descendent of the now extinct English White Terrier. The Bullmastiff was also once a popular cross-breed between an English Bulldog and a Mastiff.

Bull Mastweiler Activity Requirements
The Bull-Masto (or “Bull-Moose Dog”) is a relatively new hybrid dog that was created by crossing the American Pitbull Terrier with the Neapolitan Mastiff. They are large, muscular, and gentle. While they are not a very active or intense breed, they do require regular exercise. They can become destructive if bored, so it is important to provide your Bull-Masto with activities and toys they can play with throughout the day. They need about an hour of exercise and playtime each day. This can be done in several short sessions or one long session. When walking your Bull-Masto, remember to use a strong leash and be careful around other dogs.
