I dont own pit bulls, but I beleive that any dog can have a tendonsy to be an agressive killer. I am in my early thirties and remember when rotts and dobies were considerd visious killers and were being banned, thats not so much the case now. I have read some of the posts and have to agree that most animal behaviors are a direct result of the human factor. I also beleive thought that there are some animals, no matter what kind of person you are to them they are predisposed to certian temperments..but thats across the board, all animals have that possibleity..NOT just with the aggressive "pits" hell chahuaha's are a mean lil dog ( by reputation)..Just ppl arnt scared of them. I am scared of dogs, but I still think its (blankn) rediculus to ban only ONE breed of dog. (sorry for spelling errors)
