Good ideas above. Also a bundt cake pan. Or try spreading the food out on a cookie sheet. Hell, go out in the yard and find a couple of heavy rocks or a piece of brick, wash them off and try them. That's what I did when I worked with explosive detection dogs.
I did the smaller bowl inside the feed bowl with one of our greyhounds. If I was in a good mood, I actually put food in the bowl. :rofl
I cannot see spending that much money on a bowl.
