Splitting an antler down the middle changes it from a hard outer shell into a chew with two different textures in one piece, which is exactly why some dogs prefer a split antler over a whole one.

This is a Highland Split Antler: the outer shell stays hard, while the honeycomb marrow inside is softer and easier to work on, which suits a puppy, an older dog, or any dog that likes to get at the marrow specifically. It is naturally rich in minerals and calcium, and being unprocessed it carries no odour and creates little mess, since the dog grinds it down gradually. It comes in three sizes.

• Split down the middle, exposing the softer inner marrow
• Hard outer shell, softer honeycomb marrow inside
• Rich in minerals and calcium
• No odour, and little mess as it wears down
• Comes in three sizes
• Suitable from 12 weeks

On sizing. As with any antler, colour and exact shape vary piece to piece because it is a natural product rather than a manufactured shape, and no weight figure is published across all three sizes here — choose against your own dog's chewing style rather than assuming the largest is automatically safest, and remove any piece that has worn down small enough to swallow.

Who it's for: puppies, older dogs, or any dog that finds a whole antler too hard, and owners who want the same natural chew with an easier way in.
