I have wrought iron one's for my two. I chose the single bowl style because somebody around here (Chan) is a backwasher...lol!
Phoebi has a fit if there's kibble crumbs in her water so I bought two and keep them a few feet apart. This way Chan's crumbs fall off before he takes a drink.
I have the smallest size...it's 5" off the ground.
Oh...forgot to say...I did have a wooden one when it was just Phoebi. Over that year it did get a little "icky" from her water dribbles.
