I never had strong feelings about pitbulls one way or the other. Never knew anyone who owned one.
The way I was brought up, you never allow animals to be a threat to human beings. Animals have natural defenses and senses that human beings don't.
After seeing what they are capable of, to my mind, they're just not-so-little, anti-social killing machines. I'm sorry that human beings ever created them.
For the life of me, I don't understand why anyone would choose that breed of dog.
Having been viciously attacked and scared for life by a Cocker Spaniel, for the life of me, I don't understand why anyone would choose that breed of dog.
Anyone who lets their dog out on a regular basis daily to roam the neighbourhood without any supervision as you've practiced should not be IMO allowed to have a dog.
You blindly refuse to take any of the responsibility here so it's useless wasting any more time on this subject.
