I have not been on in awhile due to college so I am unfamiliar with the food issue with your boy Bogey (love the name, btw).
I know Momo gets a bump everyonce in awhile on her chin and my boxer did, too. I've learned over time that it can come from plastic bowls (so I stopped using them) and/or metal bowls that aren't changed often enough. In no way am I saying you feed Bogey out of dirty bowls. I'm just sharing what I've experienced over the years. Is it possible that his ear problems could be allergy related?
Hope this helps. Good luck.
