I am a 24 year old mother of 2 children and I own three pit bulls. They are all inside dogs and are THE best dogs I've ever owned. My mother had her retriever mix at my house and he tried on more than one occasion to hurt my oldest one, she never even gave him a second look. They "look" mean is how my mother puts it but her shitzus are constantly biting my dogs have never bit anyone or anything. There are idiots out there who abuse their strong will and power and train them to do horrible things but please don't judge these animals on the inhumane acts of humans.
