My 11 month old puppy loves to chew. These cheek rolls were recommended to me as an alternative to rawhide chews. She adores them. I give her the large roll for about an hour a day, and it lasts for five or six days. My one issue - which is, of course, understandable given that they are made from cow cheek is that they don't smell great. Other than that, fantastic and more cost effective than the rawhide chews I used to purchase.
