exactly. but both sides agree that the dog got loose and that fact is key. a person unfamiliar with the dog, much less a pitbull, won't know if an approaching dog is friendly or not. a wagging tail does not necessarily mean the dog is friendly. everyone knows pit bulls are capable of causing grave injuries and who would want to take a chance if an approaching pit bull is friendly or not?a loose chihuahua is a different story. sure the bite would hurt but it's not going to kill you and besides you could probably punt it away 30 yards if you had to. so a loose pit bull? cholo is going to have to side with the officer on this one as much as cholo hates trigger happy officers.
