I've met people who literally allow their dogs to bite and I've never understood it. I did learn about puppy's bite inhibition, though. And I know that's usually worked on with their littermates, owners, and new pup friends. But these folks didn't even have puppies, they were adult dogs that would do this....like you're just cool with being bit everyday?

Tyson pretty much has it down that biting is not cool, and we mostly implemented the "walk out" move. We would go over to the den where he's barred off. Eventually he gets it, lays down, and waits for us to come back. The only time we really see it happen is when he's way too over excited. When we cry out loud enough he ends up licking the same spot apologetically.
