I'm so sorry Anna. Stuart and I have both been bitten in the same situation--breaking up a fight. In the middle of a fight, a dog's brain has turned off. They are running on pure instinct and adreline. Bon probably had no clue that he was biting a human, especially his human. Breaking up a fight safely is very difficult. I have way more experience at it than I'd like and sometimes still do it all wrong! Sometimes the only way to stop a pack fight before someone gets killed is to wade into the middle and start flinging dogs off each other!
