Pit bulls have been MADE into a breed that kills people, but remember, all dog breeds are the same species. It is entirely possible to breed a dog that looks like a pit bull but behaves like Lassie, and whatismore, it only takes a dozen generations or so (about 20 years) due to dog's remarkable genetic flexibility.
The behavior is not bound to the look.
It is entirely possible there are lines of "pit bulls" that are docile and not a threat, and there are other lines that have been bred recently to be aggressive, and still have those genetic behavioral tendencies.
This is why only certain breeders should breed and sell those breeds, because only SOME breeders have a history of responsible breeding to select for behavior.
Unfortunately, because of the bully breeds' dog fighting history, many of the pitbulls out there have been bred, presently or recently, for aggression as junkyard or fighting dogs or other negative behavioral traits, and jackass breeders keep putting those back into the gene pool instead of eliminating them or at least neutering them.
I'd love to know if the dog was from a puppy mill or a backyard breeder. The "domestic disturbance" call is a hint about the lifestyle and environment the dog might have been raised in. Someone that is violent towards people may have been violent towards dogs, and sure as hell the dog will learn, too.
It still amazes me that tens of thousands of pit bulls go to AKC events every year, around hundreds of thousands of other dogs that they're supposedly bred to fight, and around hundreds of thousands of other people, and there is virtually never an incident. Perhaps it is because the behavioral breeding is more tightly controlled as AKC has a pretty much zero tolerance policy for dog bites or attacks at AKC events. Lifetime ban.
