The only dog that's ever bitten me was the Cocker Spaniel of some friends. While they were out of town, I went to their house to feed their dog, who was in the backyard and had a very nice doghouse for shelter. One day, as I put down his bowl of food, the dog attacked me, biting my arm. Fortunately, it was cool weather and I was wearing a flannel shirt that protected me. The shirt was torn but my skin was only bruised. Ever since, I don't trust Spaniels!
