The person with the twisted sense of humor in me wants to say run around him and bark when he eats and see how he likes it(boy is that a mental picture), but guess that might not work. lol
(Sorry been a long crazy Monday.)
Don't know if it's possible for you but I restrict mine from the kitchen. I've noticed lately he might get antsy when I am preparing something, and I chalk that up to him no knowing if I'm cooking for me or getting his canned food ready, but as soon as he sees me sit at the kitchen table he knows it's not for him and he quiets right down.
I'm sure someone will give you a better solution, I know it's frustrating.
