This is my grandparent's dog, Dixie. She is insane, one minute she'll let you pet her and next minute she is trying to chew your leg off. We figure she must have been badly abused by her previous owner. For some reason, everytime she gets food, she starts growling and trying to bite her own butt, like she thinks her butt is going to steal her food.
