We have Newfoundlands, so as cool as the Instachew Puresmart App Connected Pet Water Fountain is, it's a bit too small to handle their water needs. BUT, it has been perfect for our foster cat and kittens. We placed the fountain on a counter so the cats could easily access it. They were thrilled to be drinking running water. The fountain is quite impressive. It holds a nice amount of water, and the pump is super quiet. It has a fantastic water cleaning system with an easy-to-clean filter and a built-in UV light.  The cats love it!  And, if it ever comes in a super-size, we'd get it for our dogs.
