My big ol 12 month old labradoodle loves these rawhide chewy bones. They hold together during the chewing process. Typically one will last 3-4 days. They really do the job on the chewing urge. He is the ultimate game creator and player. His favorite is when I roll these up in a rag bath towel and he gets to sniff, paw, bite and find the bone. Fun stuff. I like the size of the bones and the amount the comes in a package as we go through these on a regular and consistent basis. Easy to recommend if you have a dog who like to chew.
