I just got the Premier Pet™ 60 oz. Pet Fountain, it is perfect for my 22lb mini poodle. Set up was easy and my dog drank right out of it with very little coaxing   I like that it is higher so my dog's ears do not get wet when he drinks. It is easier for him to drink out of since it is higher.  It is quiet. It comes with a carbon filter that you will have to replace every so often but I use filtered water so it should last me a while.  I think it us really cool. I would recommend it for your small dog or a cat.  My family is happy to have it for our dog, get drinks a lot.
