This chew is made from a single ingredient: naturally shed deer antler, sourced from wild deer rather than farmed or harvested animals. The antler is split or left whole depending on size, exposing the nutrient-rich marrow inside that dogs find appealing. Antler chews are naturally odor-free and mess-free, since the material does not require added preservatives or artificial flavoring. Because the antler is slow-grown in the wild, it resists mold and odor without chemical treatment. Chewing on the dense antler surface can help scrape away plaque and tartar during normal gnawing. Owners are encouraged to start younger or new-to-antler dogs on half pieces so the marrow center is immediately accessible. Fresh water should be available whenever a dog is given this or any hard chew.
