To begin, simply introduce your dog to an antler. This can be done through the use of an actual shed antler or a store-bought foam training antler. If your dog is cagey about carrying around hard bone, the store-bought softy is the way to go. Otherwise, choose an antler that is small enough for your dog to easily pick up. If your training antler has long, thin tines, consider sawing them off so they won't accidentally poke your pup during an enthusiastic retrieve.
