Have you ever heard an aggressive dog owner after an attack say "oh I knew Cujo would do that he has always been kind of snotty"?
NO they say I don't understand tinker bell has never been aggressive he sleeps with my babies every night.
There are certain breeds that when they do attack they are relentless and injuries or death result
Don't tell how many times you have been bitten by a Chihuahua, nobody has ever been killed by a 5# dog.

As an afterthought have you noticed how many of these Bully breeds attack their own family members or friends? I will never trust them.
