My dogs still aren't sure how they feel about this, but are slowly warming up to it. I like the idea of filtered water that stays fresh all day. It is easy to fill and clean and comes with 2 extra filter covers for the water. It is quiet and adds a certain ambience to the dogs dining area. It is a perfect size for my Brittany; but my English Mastiff can use it as well. I just have to fill it up more. It is a great size for cats as well.
