Most Common Breeds of Dogs That Bite

Supervision of dogs around children is especially important, as the majority of dog bites that result in injury or death happen to children. The table below shows data from 1982-2014 dog bites by breed and injury type. 

Although genetics do play some part in determining whether a dog will bite, other factors, such as whether the animal is spayed or neutered, properly socialized, supervised, humanely trained, and safely confined, play significantly greater roles. Responsible dog ownership of all breeds is the key to dog bite prevention.
