Years ago, when I had Charlie, we found some hard plastic bowls shaped like a rectangle. We got two, and Charlie and now Frankie used them. Both dogs have chewed the base of them and they do need to be replaced. But I have never seen them again, and I have no idea where we got them. They work amazingly well. The ears hang over either side. If anyone knows where we can get them, I'd be pulling out my credit card in a flash!!!
