DO NOT buy this product if your dog is large or has strong jaws.I am always searching for good chewing toys for our 1 year old Great Dane. (Note that she is in the lower 10th size percentile for Great Danes, so she's not even that monstrously large or strong.)She was able to crush this bone into hundreds of tiny sharp pieces within minutes of chewing.Also, the product was very greasy and left grease stains on her dog bed.I had purchased three, but I threw the other two away with the collection of splinters from the first.
