PETMEX deer antler half M is a natural, exceptionally hard chew that provides long-lasting entertainment for medium breed dogs. It’s made from carefully selected antler sourced from natural deer shedding, making it completely free from preservatives and dyes. Being split into halves makes it easier to chew, which makes it an ideal choice for dogs that go through most chews quickly. The odorless structure of the product makes it pleasant for owners with a sensitive sense of smell as well. It’s a natural source of calcium and phosphorus that supports the health of bones and teeth, and the mono-protein venison is excellent for dogs with allergies. Chewing the antler helps maintain oral hygiene, naturally removing dental plaque.
