It wasn't his fault. There was another much larger dog who was bothering our little group - three dogs. His owner was trying to control him but he was young and daft. I already know I should have handled it better but I picked my medium breed dog up as he was getting really riled and I just wanted to get him out of the way. He couldn't have held his own against the big dog and I was worried he'd be hurt. The bothersome dog jumped up and my dog bit hard to make me put him down I think. He's broken the skin on my arm though a hoodie and padded coat so it was a full on bite. I'm not sure if he was going for me or the other dog but he's very quiet and ashamed now. He's not a fighter, though will never concede ground if he feels threatened, he always minds his own business unless threatened, never goes looking for trouble.
Just feeling a bit sad and rubbish really. He's never done that before and he's way back under the table, clearly feeling horrible and I feel like a bit of an idiot
