The bullmastiff dog breed is among the loyal and trusting breeds. This canine is neither a bulldog nor a mastiff- it is a combination of both. Therefore it inherits both of their characteristics. The canine is not only the best companion for your kids but also enjoys the body hugs and belly rubs that you give him. However, this does not make it less alert or active.
Developed in the mid-19th century, these canines were one of the strongest breeds. In the 1890s, the gamekeepers needed a fearless breed. There had been several experiments for forming this breed but nothing seems to truly work. Finally, when the bulldog was made to breed with a mastiff, it created one of the perfect dog breeds. The Bullmastiff dog breed not only had the caring personality of the Mastiff, but also the aggressiveness of the Bulldog.
The appearance of a Bullmastiff is enough to hold down an intruder. In 1933, the American Kennel Club came to recognise this as a breed.
