A 1991 study found that 94% of attacks on children by pit bulls were unprovoked, compared to 43% for other breeds, and that 67% involved freely roaming animals.
A 5-year (1989–94) review of fatal dog attacks in the U.S. determined that pit bulls and pit bull mixed breeds were implicated in 24 (29%) of the 84 deaths in which breed was recorded
A 20-year (1979–1998) study by the American Veterinary Medical Association into fatal dog attacks on humans concluded that "fatal attacks on humans
appear to be a breed-specific problem (pit bull-type dogs and Rottweilers)," and that "pit bull-type dogs and Rottweilers were involved in more than half" (67%) of all the 238 recorded dog bite-related fatalities (DBRF) in the United States during that period, with pit bulls accounting for 66 deaths.
A 15-year (1991–2005) review of dog attack fatalities investigated by the Kentucky Medical Examiner determined that pit bulls were implicated in 5 of the 11 fatal attacks (45%). Another 15-year (1994–2009) review of patients admitted to a Level I Trauma Center with dog bites determined that pit bulls were most often involved in these attacks: of the 228 patients treated, the breed of dog was recorded in 82 attacks, and of these, 29 (35%) of the attacks were by pit bulls. In 45% of the attacks, the dog
belonged to the victim's family.
A five-year (2001–05) review of dog attack victims admitted to the Children's Hospital of Philadelphia determined that pit bull terriers were implicated in more than half of the bites where breed was identified. Of the 269 patients where breed was identified, 137 (51%) were attacked by pit bulls.
A medical literature review of animal-related fatalities, citing the 1979-1988 JAMA study and 1991–2005 Kentucky Medical Examiner study, reported that pit bulls and pit bull cross-breeds were involved in 42–45% of dog attacks, and that unneutered male dogs were the most likely to bite. Fatalities were most often reported when children were attacked, with 70% of victims being under the age of 10.
Not at fucking all. Let's use feelings and not science because reasons. I know a guy with a pit bull that didn't do anything so they must be nice dogs.
I mean look how cute this one is! He's smiling
