Our sister's dog has the best bowl for his food. It's a big enamel bowl from George, and there's just something about it that works perfectly.
Well, actually, there are several somethings -- the size, the sloped sides, the rubber ring along the bottom that prevents sliding, the ease of cleaning, as well as the look.
Coop has two in green - one for water & one for the chow. He digs 'em. And they're easy to clean (for me, not him).
My guy has one in yellow - it looks pretty cool next to the ceramic George water bowl which says water on the bottom...And, it doesn't bother me to see it in the kitchen...
