Since I missed out on the other thread, thought I'd start one here.
I have six german shepherds. I can go to any one of them at any time and take whatever it is that they have, be it a food bowl, a fresh meaty bone, whatever. Or I can call them to me and ask for a drop it and get the item. Four of my six eat in their crates. Tyler and Sheba respect one anothers bowls and pretty much eat at the same rate so they do fine in the kitchen. The other four would be asking for food stealing, so they don't get the chance. And being that there is one of me, I can't be in all places at all times, so crates it is for meal times.
I taught my children not to bother the dogs when they were eating or sleeping. My oldest was about 18 months old when he bothered Linus and got bitten for his efforts. I didn't need to reinforce that. However, I did need to work with her. She normally was not a resource guarder, but this had been a horribly hot and sticky day and she was cranky, as were the rest of us. I've never since had a dog that couldn't be "bothered" when s/he was eating. At least not by humans. I don't care if they warn each other off their bowls, but by golly they better not warn ME off! Or any other human. While I might teach MY children proper respect for animals, that doesn't mean that others do the same.
My niece dropped by with her two little ones. Her 4 year old is a hellion on wheels and does not listen. Gracie immediately went to Tyler who was still eating his breakfast and gave him a hug. He gave her a look that clearly said "I'm eating. Can this wait?" and that was it. AFTER he finished, he went to her (by that time we had corraled her, no small feat) and gave her kisses. I know that my niece TRIES to teach the right stuff with her daughter, but they don't have dogs in their home so it's a bit harder, and this child only listens when she wants to listen.
It's my job to protect my dogs from the Gracies of the world, but, when it's 10 degrees do I ask them to wait outside for the five minutes it might take my dog to finish eating? Do I take my dog to a crate when someone drops by unexpectedly? I should have, but I didn't. In they come and if she makes a break for it while I'm removing her coat and makes a beeline for my dogs, well, my DOGS best be bombproof. I can't teach all the children of the world to respect my critters, so I'd best teach my critters to respect THEM.
Now I don't bother my dogs while they are eating.....in most cases we're talking minutes to inhale their food. But if I need to get to something in the area of the bowl, I excuse myself, touch them and relocate the bowl if needed. Not an issue, nor should it be. And I'd best explain that so I don't get flamed.....it'll go something like this "hey sweetie, mom needs to get in that cupboard, lets move over here to finish". No muss, no fuss.
But the point is, I can do whatever I want when they are eating, and that's as it should be.
