I tried the dispenser type waterer with the cats. Didn't like it. They'd get food into it and that would float up and disintegrate and the whole bottle had to be dumped. The food wasn't always from the food dish; Chestnut loves to go for a drink when he still ahve a mouth full of food.

If it is a fountain type, then it needs power to run the pump. I don't think any of them are battery operated, would take too many batteries.

For smaller dogs, the idea of the lixit is suggested on some of the club web sites, but using a bottle like for rabbits. Attached to your crate. Also suggested for white dogs, to prevent the staining.

Applesmom, I know we couldn't use anything like the lixit here. We turn the outside water OFF for the winter, then drain them, so none of those pipes freeze and burst.
