Hi there. I have a hypothetical question about a dog with food guarding tendancies towards its owner. ( I don't have this problem, I overheard someone talking about it and I wondered what you thought) Dog stiffens up, growls, as owner approaches bowl, so owner takes bowl of him briefly. At the next meal, the owner does it again, ignoring the stiffening and growling so the dog snaps at the owner, owner smacks dog and so it goes on and on until the food guarding is a major problem. How would you deal with this. Thank you.
