Bite Force Of A Bullmastiff

There are many myths and a ton of misinformation surrounding the controversial issue of dog bites. You may have heard things like Chihuahuas are the breed most likely to bite (impossible to say) or that Pit Bulls have locking jaws (absolutely not true).

That misinformation continues when it comes to the force that various dog breeds can bite with. You’ll hear that one breed or another has the strongest bite — Pit Bulls, German Shepherds, and Rottweilers are the usual suspects — or you’ll hear seemingly incredible figures listed for just how hard those pups can chomp down.

Here, we look at which breeds actually bite the hardest and just how hard (measured in pounds per square inch, or psi) that they can bite.

556 PSI

English Mastiff

The Mastiff is an excellent family dog, but they can get quite large. Theyre passionate and are suitable for kids. One thing to note here is that theyre watchful and can be trained that way. Theres a difference between being attentive and angry or aggressive. The Mastiff does have a bite force of 552 PSI, so its important not to anger the dog or have it around strangers until it is fully trained.

Alano Español – 227 psi

These large dogs are descendants of the bull-baiting dogs of Europe, and before that, the war dogs of the middle east. Serious and calm, these canines are not hyper, in-your-face yappers.

Wary of strangers, this Spanish bulldog needs strong, “pack leader” training to keep from becoming dangerous. These pooches are known to be difficult to housebreak. They may do better than outside dogs.
