What this isThe Medium Deer Antler Chew is a naturally shed deer antler, Grade A, sourced in the USA, measuring approximately 5 inches long and 2-3 ounces. It is sized for dogs 25-45 lb.Antler chew sizing by dog weightCorrect sizing is the first control on chew safety. A chew that is too small can be swallowed or lodged; too large and most dogs disengage. Match the chew to body weight first, then to chew style. Size Dog weight Approx. length Small 5-25 lb 4 in Medium ← this product 25-45 lb 5-6 in Large 45-65 lb 6-7 in Extra Large 65-85 lb 8 in Giant 85 lb and over 9 in Which dogs this size fitsThis chew is intended for dogs weighing 25-45 lb. Weight is the starting point, not the whole answer — chew style matters as much as body size: Gentle gnawers work at a chew slowly. They can usually take the size matched to their weight. Power chewers apply force with the back teeth. Size up, and supervise more closely. Dogs that have fractured a tooth before should not be given antler. Choose a softer chew type. Split or whole: which to chooseA whole antler keeps the dense outer shell intact around the marrow. It takes longer to get into and lasts longer than a split antler of the same size. Dogs new to antler sometimes ignore a whole one at first — if that happens, a split antler is the easier introduction.Deer antler is generally harder and denser than elk antler, while hardness still varies by the antler section and whether the chew is whole or split.How to use this chew safelyAntler is a hard chew. Veterinary opinion on hard chews is genuinely divided, and tooth fracture is the risk most often raised. We would rather tell you how to reduce that risk than pretend it does not exist. Supervise every chewing session. Do not leave a dog alone with an antler. Introduce it in short sessions of 10 to 15 minutes before allowing longer ones. Match the size to the dog using the table above. Take the chew away if your dog is biting down hard with the back teeth rather than gnawing. Provide fresh water alongside. When to retire this chewReplace the antler when any of the following is true: It is worn down small enough to fit entirely in your dog’s mouth. It has developed a sharp edge or a split that catches your fingernail. Your dog is swallowing fragments rather than shaving the surface. Store it dry between sessions. A damp antler left in a bowl can develop surface mould.Which dogs should not have an antler Puppies still losing deciduous (baby) teeth. Dogs with existing dental damage, or a history of a fractured tooth. Senior dogs with worn or brittle teeth. Dogs that swallow pieces rather than chew them down. If you are unsure, ask your veterinarian before offering any hard chew.SourcingHeartland Antlers is a veteran-owned business. Antlers are naturally shed — deer and elk drop them annually and regrow them — and are collected rather than taken from an animal. All antler is sourced in the USA.Frequently asked questionsWhat size antler does a 25-45 lb dog need?The Medium size is matched to dogs 25-45 lb. If your dog is a power chewer, choose the next size up.How long does an antler chew last?It depends on the dog and the cut. A whole antler lasts longer than a split antler of the same size, because the dense outer shell has to be worked through first. We do not publish an average because chew rates vary too widely between dogs to give a number you could rely on.Is an antler chew safe for my dog?Antler is a hard chew and carries a tooth-fracture risk that veterinary opinion takes seriously. It is not the right chew for every dog. Follow the sizing table, supervise every session, retire the chew when it is worn down, and check the exclusion list above. If your dog has any dental history, ask your vet first.
