Classified as a Working Dog with the American Kennel Club (AKC), the Bullmastiff characteristics include: nobility, attentiveness, and intellectual look. The Bullmastiff is distinguished from the English Mastiff by its smaller compact size. Bullmastiffs are often described as intelligent, loyal, protective, stubborn, family-oriented, playful, easy-going, passive, and moderate exercise to maintain muscle structure and good health. They are easy to train in conformation, obedience, and/or search and rescue. They are protective of their family and property, and are excellent with children.
The Bullmastiff tends to be a domineering animal wanting to take control. It is important that they learn who the master is from day one to minimize any potential behavior problems. This breed should be socialized with other animals, as well as people, from an early age.
