Pit bulls are far more likely to be violent and aggressive than other dogs, suggests Charlotte Alter of Time. They form only 6% of all dogs in the US but were involved in 68% of dog attacks and 52% of dog-related deaths since 1982. The CDC found that between 1978 and 1998 pit bulls killed more people than other breeds. According to one study from 2011, pit bulls kill a person every two weeks and injure a person twice a week. The only reported killings by shelter dogs, between 2000 and 20009, were committed by pit bulls. Some argue they have been bred to be more violent and are therefore more dangerous than other dogs.
Pit bulls, like all dogs and humans, are a product of their upbringing. They are not inherently more violent or aggressive than other breeds, holds The American Society for the Prevention of Cruelty to Animals. While the original purpose of pit bulls was to fight bulls, bears or each other, many of them have been bred to be docile and friendly since. Today’s pit bulls are mostly the product of random breeding, watering down any aggressive traits. The people that raise them have a far bigger effect on their behavior than their genetics. Failing to socialize them properly is much more to blame than any supposedly aggressive traits.
