Bullmastiffs are powerfully built, and their imposing size gives them an intimidating look. One even kept Sylvester Stallone's character company while he trained in the film Rocky. But this dog is a lover, not a biter.
Originally from England, this large and medium-energy breed can grow to between 100-130 pounds and lives an average of 8-10 years. The breed is recognized by the American Kennel Club and classified as a member of the Working group.

Bullmastiffs are calm and polite housemates (if you don't count the drool). They love being part of a family.

CARE & HEALTH
HOW MUCH DO BULLMASTIFFS SHED AND WHAT ARE THEIR GROOMING NEEDS?
Grooming is relatively easy with a Bullmastiff. Their short single coats are coarse and straight. They're average shedders. Brush them about once a week, and be sure to clean and dry out those deep wrinkles to avoid infection. You might want to bring a towel or dog-safe wet wipe with you to deal with the drool.
WHAT HEALTH PROBLEMS DO BULLMASTIFFS HAVE?
Though generally a healthy breed, some Bullmastiffs are prone to cancer, bloat, and hip dysplasia.
Feeding your baby Bullmastiff a growth food for large-breed puppies will slow their rate of growth but not diminish their adult stature, and may help prevent or reduce the impact of adult-onset hip dysplasia.
