More Illinois families buy dogs every year, and while most dogs never bite or injure anyone, more dogs mean more dog bites. Every year, approximately 4.5 million dog bites are estimated to occur in the U.S. and around half of these bites happen to children. The vast majority of these bites cause no or very minor injuries and do not need medical treatment. But certain dog breeds are notorious for biting aggressively and, once having bitten, not letting go—which is when the most serious injuries occur. Here are the breeds most commonly responsible for serious and fatal dog bites in the United States.
Pit Bulls
Despite making up only six percent of the U.S. dog population, pit bulls are responsible for about 65 percent of fatal dog bites. Pit bull attacks in particular cause serious injuries because they tend to bite in more than one location, to attack without provocation, and to attack strangers. While many pit bull advocates say that when a pit bull is properly raised and trained, they can make great family dogs, pit bulls are often bred and purchased by people who intend to use these dogs as guard and attack animals.
Rottweilers
Like pit bulls, Rottweilers, which are often bred to act as guard dogs, have a powerful bite force of 328 psi (pounds per square inch) that can deliver dangerous injuries in an instant. Rottweilers follow immediately behind pit bulls for most deaths, although they are responsible for only 10 percent of fatal bites. In general, dogs with shorter, wider heads bite more often and the strength of their jaw muscles and their unwillingness to relinquish after a bite is part of what makes their bites so dangerous.
