Loved this at first but if your dog(s) wear tags on their collars l Iike mine do it will get caught in between the metal frame near the bowl. I bought 3 for my big babies and Mr. Nervous Max got his caught and it scared him from using again. Ms Koda Vear  got hers caught too. 2 out of three is a design flaw. Maybe you could put flex foam in tge cracks?
