I dont blame you for not sticking your hand in there, way too many big teeth. And you know some dogs have issues, it can be hard to work with, one thing that came to mind about Wangus, is that he lost his mom straight away when born, you got him early and he has the hip problems and is not yet filled out and is on the small side, so maybe he without anyone really thinking about it, has been babied, I know I probably would, God knows I baby Galahad (at least hubby thinks I do) So maybe now when he is getting to be more grown up and thinks he can climb the ladder, it will take some work, he has always been the little baby not having to really do much to please mommy, just looking pretty has done it.
Good Luck though, and tell him, he cant be eating his mom, aunt marit will be mad at him, she needs his mom to talk to.
