I think I get where you're coming from but I've come across a lot of defensive/possessive dogs and none of them have bitten before. To be clear, it wasn't playful, there's a big old flap of skin and a load of exposed flesh. Credit to the other dog owner though, he was very apologetic, said it had never happened before and gave up his contact details. Hopefully he'll be more careful in future.
