Bullmastiff vs Mastiff

Bullmastiffs are affectionate, happy-go-lucky dogs who form deep bonds with their humans and are faithful companions. A cross between the easy-going Old English Mastiff and the courageous Bulldog, the Bullmastiff dog is the perfect combination of their traits and makes a lovable guard dog.

Even with their guarding instincts, this big softie isn’t much of a barker. They were bred to spot, track and pin down poachers, and they had to be silent to achieve this mission—truly, they are the ninjas of the dog world. You wouldn’t know they were around, except they’re usually leaning against your leg or trying to fold themselves into your lap. (Wherever you are is their favorite place to be.) And don’t even think of leaving them outside on their own. They’ll be at the back door waiting for you to let them in. With their lovable personality, it’s no wonder they are the 61st most popular dog in America.

Bullmastiffs are not really aggressive, nor are they known for biting (even though they have a powerful bite force). Like most working breeds, they are confident and self-assured protectors of their domain and can be wary of strangers. So, start training your Bullmastiff puppy early to help get them used to having visitors in your home.

Because they are large dogs who often think they are toy-sized, they can be a bit clumsy around small children, cats and smaller dogs. So, be sure to keep an eye out when your Bullmastiff dog is around anyone smaller than them.

Extreme loyalty and a courageous nature are the defining characteristics of a Mastiff’s temperament. While a Mastiff’s massive weight and height may put off some potential pet parents, this breed is quite friendly and makes an excellent family pet. If little ones are in your mix, know that with early and consistent training, having a Mastiff with kids is very doable since aggression, barking and biting aren’t common to this breed. Their kindly personality extends to four-legged pals as well, which means you can add this colossal canine to homes with cats and other dogs.

A Mastiff has competency in spades thanks to their innate intelligence and eagerness to please. As a quick learner, the Mastiff thrives on service, perhaps because this working breed has a long history of guarding and fighting alongside soldiers in battle.

It may seem counterintuitive that such a large animal might not have deep energy reserves, but this is actually the case with the Mastiff dog breed. Slow and steady wins the race here, so low-key pup parents are often the best pairing for this majestic creature.
