Splitting an antler exposes the marrow cavity and the nutrient-rich marrow inside. That exposed marrow adds flavor and makes the chew more appealing, encouraging dogs to gnaw longer.
Because antlers are hard and dense, sustained chewing helps scrape away plaque and tartar and supports healthier teeth and gums through extended gnawing.
Listings commonly describe antlers as a natural source of minerals, especially calcium, phosphorus, and zinc, and often call them rich in essential minerals.
Care instructions typically recommend spot-cleaning or wiping antlers with a damp cloth and storing them in a dry place until next use.
Many listings state the antlers are naturally shed (wild-shed) and responsibly collected in the USA, then cleaned and hand-split or hand-cut to expose the marrow. Several listings note no chemicals or preservatives are used.
Product labels and descriptions commonly target Large antlers for dogs around 30–50 lb and XL/X-Large antlers for dogs over 50 lb.
Common listing advice: supervise dogs while they chew, store chews in a dry place, discard a chew once it becomes too small, and watch for and remove any small splintered pieces.
