Ha, yes, I thought we were going to debate about whether or not to eat dogs, or what seasoning goes best. ;-)
So I am in your camp -
we leave our dog alone when he's eating and I told my kids never to touch/bother him when he's eating.
The few times when I've carelessly "reached in there" (i.e. forgot to add his glucosamine tablet, refill the water bowl, etc) he has had zero reaction. He also lets me take his Kong and thump it for him so the last bits fall out.
I do wonder if taking their food away/interrupting their eating generates feelings of anxiety and stress around eating, and can actually heighten food aggression?
And "feeding from your hand" is different from "taking away the food bowl", I think. I think it feels different to the dog - knowing owner controls food and can give it food, feels different than eating your food and having the owner arbitrarily take it away.
But there are people who say they NEED to have a dog who will never be aggressive around food no matter what, because they have small children and one never knows what will happen. But I think that even small kids (unless babies) should be taught not to bother dog when it's eating...that's good practice around any animal, for safety!
