Clocking in at a full 2 months of dry time, this is our longest drying item yet!!! The absolute TOUGHEST chew we have in our shop and guaranteed to last weeks, if not months! These horn are a very tough chew and in order to exercise optimal caution, I can only recommend to be fed to an exceptionally careful soft mouthed chewer. Contents: 1 Single Bison Horn Small - Under 12oz Medium - 12-18oz Large - Over 18oz to 2lbs On display from top to bottom shows 6oz, 12oz, 17oz, & 32oz. Similarly to antlers, these horns are 100% consumable and made up of layers of keratin with a narrow hollowed center, allowing for a small amounts of filling of your choice (and freezing) for added enrichment An ideal product for providing mental stimulation, satisfying your pup&';s satisfaction to chew, and a dental cleaning opportunity due to the unique texture of the horns Again, since this is a very tough item, I can only recommend this to the more careful, heavy duty adult chewers. The denser the chew (as is the case with antlers), the more prone a dog is to cracking and fracturing teeth. If your dog is one that bares down with full force, you&&';;ll probably want to skip this one!! Best Suited For: Heavy Duty Chewing Adult Dogs Only! Storage Instructions - No need for a freezer or fridge, this item does just fine in a cool and dry space!
