We’ve all seen doggy bowls outside stores and restaurants, subtly encouraging dog owners that it’s “all right” to come in an shop, the pooch will be OK.
Here’s a drinking fountain with the usual adult-height spray; and a lower child-height / wheelchair height. But press the top left button, and the doggy-height bowl delivers fresh water that hasn’t been left standing around where it might be dirty. And no sharing doggy saliva either.
I know more than one little child that would have been delighted to get down on hands and knees to try out that nifty low bowl.
