Bullmastiff Information

The Bullmastiff is a relatively new breed, having been developed in the late 1800s in England. The breed was created by crossing Bulldogs and Mastiffs, in an effort to create a dog with the strength and determination of the Mastiff, combined with the tenacity and courage of the Bulldog.

The resulting breed was an agile and powerful dog that was well-suited for hunting and guarding. Bullmastiffs were originally used as gamekeepers’ dogs, tasked with deterring poachers and protecting estates.

Over time, the Bullmastiff became a popular family pet, known for its loyalty and gentle nature. Today, the Bullmastiff is still prized as a companion and guardian dog.

The Bullmastiff is a large, short-coated dog breed. The head is large and square, with a short muzzle. They are very muscular dogs, with a wide chest and strong legs.

Bullmastiffs are gentle giants and make great family pets. However, they can be protective of their family and home, causing them to bark at strangers. They are loyal and loving dogs that make great companions.

Bullmastiff Exercise Needs

Bullmastiffs should receive more than one hour of exercise daily. Exercise should involve walks twice a day and playtime.

They are not suited for hot climates, as they can overheat easily.

Bullmastiffs are notorious couch potatoes, and love nothing more than lounging around the house with their family.

Bullmastiff Training

Bullmastiffs are intelligent dogs that learn quickly. However, they can be stubborn and headstrong, so patience and consistency are key when training them.

Socialization is also important for Bullmastiffs, as they can be wary of strangers.

Early obedience training and socialization will help your Bullmastiff grow into a well-rounded dog.

Bullmastiff Health Issues

The Bullmastiff is a generally healthy breed, but like all breeds, they are susceptible to certain health conditions.

Some health conditions that Bullmastiffs may be prone to include hip dysplasia, elbow dysplasia, and cancer.

Bullmastiff Grooming

The Bullmastiff is a low-maintenance breed when it comes to grooming. They have a short, dense coat that does not require much brushing.

However, they do shed moderately, so you may find yourself doing some extra vacuuming!

Bullmastiffs are relatively easy to groom, and only need occasional brushing and bathing.
