Many dog advocates argue that there is no such thing as a bad breed, only a bad owner. Still, it can be helpful to understand which breeds of dogs are most commonly involved in bite incidents or acts of aggression. Dog attacks by breed statistics are invaluable both for individuals looking for a dog to adopt as well as for those who interact with animals who want to minimize risk.
The breed that commits the most attacks overall is pit bulls.
Pit bulls are involved in more dog attacks than any other breed. In fact, the American Animal Hospital Association reports this breed was responsible for 22.5% of bites across all studies. Mixed breeds were a close second at 21.2% and German Shepherds were the third most dangerous breed, involved in 17.8% of bite incidents.⁶
The breed that is most likely to be involved in a fatal attack is pit bulls.
Pit bulls are both more likely to be involved in bite incidents and more likely to cause serious injury or death when a bite does occur. In fact, from 1979 to 1998, the Centers for Disease Control and Prevention determined pit bulls were involved in the most fatal dog attacks, accounting for 28% deaths due to dog bites during that same time period.⁷
I’ll add, I like pitties. I’ll also advise taking this with a grain of salt as so many mixed breed dogs fall into the pitbull umbrella.
