We have 3 dogs and I was unsure if all of them would like this fountain but I decided to give it a try. I originally wanted a fountain to help mix their water, see I add this mint flavor dental stuff that is supposed to help keep their mouths clean and their breath fresh but with traditional bowls I have to mix it in. With the fountain I just pour the stuff in and the fountain does all the work of mixing it in. This fountain has been a hit in our home and it makes my job easier. It's also super easy to clean since it is dishwasher safe.
