I purchased these (4 in all) in different heights as a gift to our local dog park. They are incredible and have solved a big problem of dogs putting their feet in the water bowls. Being at the park and exposed to the elements and lots of dogs, they are going through some pretty heavy duty use and holding up fine. They were a perfect solution for us. These bowls aren't cheap but they are tough as nails and I would highly recommend them. As an additional bonus, because they are raised, our older members have an easier time changing the water--not as far down to bend. You won't be disappointed with this purchase!
