Introduce upland dogs to the gun when they’re into birds and excited. Use live pigeons or go to a game farm, and make a loud noise when Pup flushes a bird. Clap hands, or use a blank pistol, and work up to a shotgun. For retrievers, have a helper throw a dead bird or favorite dummy out front while you hold the dog on a check cord. The assistant can start by clapping hands after the throw, then he can shoot a blank pistol, and ultimately a shotgun. Keep the gun in front of the dog, not behind.
