First off, I like these because the package states they have been harvested from naturally shed horn. I don�t know if that is really true, being the skeptic that I am, but it does make me feel better. Mr. Puppy does like to chew...fortunately on bones, horn and dried puzzle as opposed to his toys. He seems to enjoy having a choice of chewing surfaces such as what is offered in this pack. He doesn�t seem to prefer one over the others, which I interpret as his enjoyment of having different �chew� choices, whether it�s hardness, texture or taste differences that he enjoys, he likes them all. He is a medium size dog at 39 pounds, but like the large dog size chews very much. As with most chew products, keep an eye out when in use by your dog. You always want to watch for possible splintering, which, while rare, can occur. I also remove a chew that gets small enough to fit inside Mr. Puppy�s mouth with it closed. No choking on my watch!
