Scary! I was also bit by a lab, totally unprovoked. I walked dogs for the local shelter and was walking this lab. He was really sweet, albeit a little hyper and a bit of a puller, but you gotta give shelter dogs a break. Well, I turn around to go back to the shelter, and just as I turned, he jumped on my back and bit into my shoulder. I thought he was trying to hump me, so I pushed him down and said "no!" At that second, he just started lunging and biting me all over. He got my ribs, thigh, ankles, hands, and finally grabbed my upper arm and was shaking it. I had really deep bruises for several months and often my arm hurt for even months after that. Luckily he did not break skin b/c I was wearing my winter clothes. My DH had to run over and pull the dog off me. When he brought him back to the kennel, the other volunteers mentioned they never walked him b/c he always bit their hands and played too rough. I do not think he was being aggressive, but he was very pushy and honestly, that is pretty dangerous considering a family with kids might have adopted him. I'm 5'6" and pretty strong, it felt like he was ripping my arm off.
