Bullmastiff vs English Mastiff: What Are the Differences?

Many people think that the Bullmastiff and the English Mastiff look alike. Both are massive, have short coats and muzzles, were both originally bred as working dogs, and are extremely powerful. Also, they’re both descendants from the Mastiff lineage, so it makes sense that they would have a few things in common.

But there are differences between these two distinct dog breeds. For instance, the English Mastiff is a purebred dog while the Bullmastiff is a hybrid mix of the English Bulldog and English Mastiff. They are both huge dog breeds, though the English Mastiff tends to be quite a bit larger than the Bullmastiff. In fact, English Mastiffs hold the record for being one of the top nine largest dog breeds in existence. Here are other differences between the Bullmastiff and English Mastiff.

Visual Differences

As mentioned, both these dog breeds get quite big when fully grown. The Bullmastiff can weigh up to a whopping 130 pounds! But if you think that’s big, you should get up close and personal with an English Mastiff. These guys can weigh in at a massive 200 pounds or more. One English Bulldog holds the weight record at 343 impressive pounds!

Both the Bullmastiff and English Mastiff have similar body and head shapes, but the English Mastiff’s features are obviously larger. English Mastiffs are born with either fawn, apricot, or brindle coat colors. Bullmastiffs typically feature fawn, red, or brindle coat colors. English Mastiffs always have a black mask, while the Bullmastiff’s mask could be any of the mixed breed’s coat colors.

Personality Differences

Both the Bullmastiff and the English Mastiff have been bred for hunting, so they have strong prey instincts to contend with as owners. Both are intelligent enough to pick up training quite quickly. However, the Bullmastiff is quite a bit more active than the English Mastiff.

If the Bullmastiff isn’t sufficiently exercised training, the session can become frustrating for everyone involved. On the other hand, English Mastiffs are quite lazy and tend to take to training well even after a day of lounging around at home. In fact, English Mastiffs are lazy much of their free time. After a nice walk in the morning, they’ll happily spend the afternoon napping.

However, Bullmastiffs will likely want to take advantage of a play session in the yard even after an extensive walk around the neighborhood. English Mastiffs don’t need much stimulation to stay satisfied with their lives, but Bullmastiffs need access to puzzle toys and plenty of game time with family members for high quality of life.

No Mastiff is “easy” to train. Although intelligent, they tend to take their time when it comes to learning new things and putting their knowledge into practice. Bullmastiffs are stubborn and don’t usually respond well to treats during training. Patience and consistency are vital. English Mastiffs love treats, though, so they can successfully be used to encourage positive training habits.

Health Differences

Both breeds are prone to the same basic health issues and live to be about the same age of 9 or 10 years old. They both eat their fair share of dog food — up to 4 cups a day, depending on their age, weight, and activity level. Both the Bullmastiff and English Mastiff are susceptible to hip and elbow dysplasia.

Bloat and gastric torsion are also common health conditions that owners of both breeds should be aware of. Blindness may even occur in either breed upon their senior years. One difference in the health of these breeds is that the Bullmastiff may suffer from brachycephalic syndrome due to their extra short muzzles.
