"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."
"
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
Pit bulls may present a greater danger than other breeds for many reasons, such as because they have been bred to be more aggressive, are less likely to back down during fights and are less likely to give a warning before a bite."
