I would

Do the teeth cleaning JB. Remember a long time ago when somebody was in here and their dog was really, really sick and we couldn't figure it out nor could their vet until they realized awhile later that the dog had a bad tooth and that was what was making them so sick.

I would be worried about giving him bones or anything like that with teeth already cracked.They also sell stuff to give your dog to stop them from eating poop if that is the problem.

Are they back teeth?

Poor Angel:(
