I think it's a natural reaction for Dogs to snap or bite, if they're in pain or startled like that. A reflex. Just as it would be for a human to push out with their hands to get something off of you that was hurting.

If my dog continued to attack though, especially at the neck, I'd be reevaluating my relationship with my dog. That, I don't think can be explained away as a reflex reaction.

I've fallen on and stepped on mine by accident. From their yelps, I'm sure it hurt, but none have ever bitten me. A mouth on me, to let me know I hurt them, was the furthest they've gone. And I of course apologized profusely and all was forgiven. I think they know when something's on purpose vs an accident.

I also don't think most people know their dog that well. How many of us have heard, "But he's always so friendly. He's never done anything like that before", right after he's attacked you or your dog?
