You should monitor your dog very carefully if you give him/her these chews. One of our dogs died as a result of eating these chews, and the other three were very ill for two days. This product is very difficult for dogs to digest and can result in blocked intestines and infection. Since the package did not contain any warnings, we thought they were harmless. Be very careful if you buy these for your dog.
Beware of this product--one of our dogs died.
