We have an outdoor fountain and our two dogs are constantly drinking out of it. So when I saw this I thought I would give it a try. At first our one dog was a bit unsure of it but it did not take her long to start enjoying it. It is a bit loud, but if you have it set all the way to the left (there is a little lever that controls the flow of the water) I find it to be much quieter. We put filtered water in it as we have a water filter system for us and I think this will cut down on the amount of time we have to clean it. Overall I am very happy with the fountain, it really beats constantly filling up bowls of water!
