You are rare then.
Almost everyone knows of or has seen an incident involving a pitbull.
I have never seen, nor do i know anyone in my personal life to have been involved in an incident with a breed thats not a pitbull.
I take my dog to dogparks all the time and see rotts, german shephards, dobermans and all other breeds playing and having fun together.
I rarely see pits at the dog park because thier owners know better than to take their dogs to a place where other dogs will be..... but one of the few times that there was a pit at my local dog park, there was an attack.
i take my dog for walks often..... twice he has been attacked by pits, never by another dog.
my cat was killed by a pit that had gotten out of thier owners yard and jumped my fence into my back yard.
It got ahold of my cat and killed it. (My wife was bit while trying to stop the attack. I was at work at the time. the dog later died from blood infection that my cat cause from scratching its face. My neighbors had to pay us 1800 dollars in vet fees from the vet trying to save our cat. The pits name was Karma lol)
Best cast that ever lived too. :-( she was my dogs best friend
