I discovered these rubberized gems through a post on the bird-hunting blog Eight More Miles and bought four of the two-quart feed bowls and two ten-quart water buckets. Total cost, $25. I was skeptical at first, because my dogs can chew through Kryptonite. Last year for Christmas I received some "chew-proof" dog toys. The next day I scooped their pooped-out remains into the crap can, along with chunks of a granite headstone, an engine block from a '78 Chevy, and a pile of scrap re-bar (kidding about the last three, but I wouldn't put it past them).
