Made of all-natural Elk antlers, these rugged, long-lasting Big Sky Antler Chews help whiten teeth and freshen breath. Since they are grown and shed each year in the USA, they’re uniquely sustainable as a chew. Because they are allergy-free and organic, they are safe for any dog. Also, they will not splinter, so they’re safer than bones. Remember to always supervise your pet while using antler treats.
