This chew is cut from a wild moose antler that has been naturally shed rather than harvested from a live animal. Antlers grow slowly, which gives the material a dense, bone-like structure that stands up to sustained gnawing from dogs that chew with force. The exposed marrow running through the center gives dogs a reason to keep working the chew, while the outer surface helps scrape against teeth during use. As a single-ingredient product, it contains no added flavors, chemicals, or preservatives, and it does not produce the odor or mess associated with rawhide chews. Each piece varies naturally in shape and size because it comes from a real antler rather than a molded material. Owners should watch dogs while they chew and remove any piece once it has been worn down small enough to fit fully in the mouth.
