These split elk antlers are sliced down the middle, exposing the soft nutritious center so that you your dog can skip the tough outer layer, making them the perfect treats for dogs who can't chew like they used to, or who would lose interest in a full round antler. They have a scent that dogs love but that's imperceptible to humans, and they won't leave behind residue on furniture or fabrics.
