Hard to kill attacking pit bull.

My Opinion.....from experience.
I owned a Pitbull years ago. I had both of my children born while Motley was alive. He never hurt them or another person. He converted many Pitbull haters into Pitbull lovers. He was the smartest dog I have ever owned....and that's a lot of dogs of various breeds. He had his nuts until the day he died. He was extremely loyal to myself and my family and my friends. A lot of his training was done by my mother while I was at work. I was more than aware of the breed as I knew then and still know many Pitbull owners. He got arrested one day for wondering around. The dog catcher, whom he did not know, picked him up and threw him in the cab of the truck with "her", and took him to jail, accusing him of being a vicious dog, much like most inexperienced people do. I had to buy a city license to bail him out.
He did however kill a few cats. I'm referring to ones that sat out of his reach on his chain in the yard taunting him. They got caught eventually.

Motley came from solid blood lines and had no interbreeding involved.

All dog owners are responsible for their dog's attitudes, actions and behaviors. Any breed can be aggressive, unsociable and mean. I am leery of Pitbulls as many owners are idiots and create unpredictable dogs, but I am leery of all dogs I can't control with a size 10 boot.
If someone is considering owning a Pitbull they have many things to consider. They require a lot of extra effort during training. They will draw conflict from many people. They also will demand a lot of love and attention and don't like to be abandoned at home as most dogs don't.

This is the opinion of an experienced Pitbull owner and dog lover.
