First off, my dog did not like it, so it is now holding 2 plants instead of bowls of water / food. The problem I had with it was that for some reason someone thought it would be an awesome idea to stick huge stickers on the inside of the bowls, and for the life of me I could not get the glue removed. I even washed it in the dishwasher TWICE, and not even that got the glue removed. Of course, I could not let the dog use it with glue all over!
