We don't use one with Riley.

When we had Brooke she didn't know how to use an elevated dog bowl. We took her to a kennel and they had them, she wouldn't touch it so from then on they had to put it on the ground. She ate standing up, but ONLY drank laying down with her arms around the bowl. She did that with other dogs around too (she didn't go to dog parks or anything) so they couldn't have any. Riley just tips the water bowl over so other dogs can't have any.
