I bought this crate bowl on-line, from Amazon, after I realized that the Lixit crate bowl I owned was plastic (many dogs are allergic to plastic bowls, and I don’t want to find out that Chloe is one of them). It arrived today, and I’ve just installed it. It’s a straightforward object: The bowl is held in a steel ring welded to a small rectangular plate, which is attached to your dog’s crate by a wing-nut, exerting pressure on another rectangular plate. While the bowl itself is stainless steel, the supporting steel ring and attachment apparatus are black powder-coated steel.
It’s inexpensive, easy to install, and I don’t believe that Chloe will have any interest in chewing on the empty steel ring (when the bowl is absent). She could, I suppose, knock the bowl up and out of its supporting ring (the bowl only rests in the ring), but I’ve positioned the apparatus low enough on her crate that she’d really have to try before she succeeded.
Please note that I chose an 8 oz. bowl for her. That turns out to be quite a small bowl, but she’s a small dog, and we only leave her in her crate for short periods of time. If you’d prefer a larger crate bowl, ProSelect offers the same bowl in a 16-oz. size.
