Nothing is small about Bullmastiffs. Along with their immense size and dominant personalities, they have big hearts and are loyal protectors. They make great guard dogs, but their stubbornness can cause challenges with training and obedience. Show them who’s boss, and they’ll stay by your side through thick and thin. Full-grown, they typically weigh 100-130 pounds and stand 24-27 inches tall.

Bullmastiffs are generally okay with older children who know how to handle dogs. Bullmastiffs can be somewhat dominant toward other dogs in their breed, especially if both Bullmastiffs are male. However, they are good around kids and can get along with pets if they’re socialized at a young age. They're relatively quiet and don't bark much.

Although Bullmastiffs are big, they don’t require as much exercise as other large working breeds. A moderate amount of exercise, like a long walk or run, should do the trick to keep them fit and happy. Bullmastiffs walk well on a leash, but their size can make them hard to manage. Overall, their exercise needs are low.

Bullmastiffs have short coats that are red, light tan (“fawn”), or reddish-brown (“brindle”) with distinctive dark areas on the muzzle, ears, and eyes. Some dogs also have white fur on their chest. This breed doesn’t shed a lot, so their grooming needs are minimal. Grooming-wise, this breed is low-maintenance.

Bullmastiffs are best suited for a home with a yard, though they can adapt to apartment life with enough exercise. Bullmastiffs don’t do well in the heat or when they’re apart from their families, so it’s better to keep them in a cool indoor setting with a soft bed nearby. They are fairly easy to train.
