You realize that the UK breed bans have not reduced bite rates in the UK at all, right? Breed bans are ineffective, because breed is not the major determinate of bite incidents. Dogs that inflict serious bite injuries are almost always intact male dogs, housed outdoors, and most chained up as a means of confinement. Not conditions that speak of responsible and loving owners.
Pit Bull Terriers and mixes thereof are the most numerous type of dog in the USA. There are literally millions of them in homes, and the vast majority of them will never bite anyone. Bite statistics by breed are massively flawed for several reasons.
First, the average person couldn't identify a pit bull accurately if it bit them in the butt. There's lots of dogs that look like pit bulls, and plenty that don't but are mistaken for them anyway. I had someone stop me in the street and ask me if I chained my "miniature pit bull" up at night so it didn't attack me in my sleep. I was walking a 12 pound Boston Terrier. My brother and his dog were attacked earlier this year by what he swore were a pair of pit bulls. It was actually a pair of English Mastiffs. A dog was shot and killed by police in my city a couple years ago after cornering an elderly man and child. It was widely reported in the national media to have been a pit bull, despite video clearly showing a purebred Boxer and the owners producing the dogs AKC papers. No correction or retraction was ever published besides in our local newspaper.
Secondly, bite incidents by breeds thought of as "gentle" often go unreported or intentionally misreported. I know a Golden Retriever who's bitten at least a dozen people, several who required medical attention. Each time the owner claims she's never done anything like that before and begs that it not be reported. Do you know how many reported it accurately to animal control? None. And I know for a fact that three of the victims told the hospital they were bitten by a stray pit bull at the owner's urging. A Shih Tzu that was in my dog's obedience class years ago, the trainer recently told me
the owners brought him back for help because he has hospitalized seven people with serious bite injuries to their faces and hands. Want to guess how many of those were accurately reported to animal control? Again, none.
I've volunteered at shelters for over two decades. I've had precisely zero pit bulls or pit mixes attempt to bite me, though they are by far the most common dog type I interact with. I have had several Labradors, Goldens, Shepherds, Huskies, and an assortment of small breeds give it a good try, though. APBTs have a higher percentage pass rate on temperament testing than almost any other breed, including the Golden Retriever.
