I was looking for a better bowl to feed raw in to my Belgian Tervuren and this was the answer. It allows for him to get his chicken pieces out of it and get all of his vitamins licked up and I just put it in the dishwasher to clean it! And they dont rust. Mine has been left outside on and off with it raining or snowing and I have no issues. I am ordering a second one for traveling to dog shows for my big boy.
