1. pit bull mix(it was my fault, I was 4 or 5 and I took his food away from him when he was eating*he was neglected when we got him and starved so he was protective of his food*, he bit my nose off and I had to get plastic surgery)

2. tea cup chihuahua(one of my aunt's rescues), she was just trying to act vicious no damage down.

3.german sheperd *Simon* a rottie got in the backyard with the dogs and Simon was upset because he doesn't like new dogs, I didn't want them to fight so I grabbed Simon's collar, I guess he thought I was another dog and turned around and bit me, he was sorry though, he immediatly layed down and looked scared, he had bit through my thumb so I was screaming pretty loud.
