This product is a choking hazard for pets. I gave this two stars because my Lab mix loved it. That said, he had torn it to pieces within 30 minutes of me giving it to him. He was able to swallow several of the pieces of rubber, and I was forced to take it away from him. If I were not supervising him, he might have been in worse shape. Please do not buy this product!
