Years ago, I found a place online that made white plastic bowl holders at various heights and sizes, it was great! How I wish I'd kept it. I have two of them...one, about four inches high that my water bowl sits in and one I use for my older dog. A stainless steel bowl sits inside the holder and raises it just enough that they dogs aren't dragging their ruff through the food and the water.
I also think it's better for them, especially as they get older, to eat with the bowl raised a bit.
My biggest problem was finding single dog bowl holders. Besides being large, they always seem either to be made for TWO bowls or, as you said, ginormous dogs. With multiple dogs, I don't want double holders, I want single ones!
I did find these online, but they're pricey:

A few more still, still expensive but a few that are reasonable:

This is the closest I've seen to what I have, on ebay, and it comes in sizes! (Still pricey though...)
