Collar Training Young pups are often bewildered or unsure of themselves and their newly acquired leash and collar. It usually takes only a few hours for a pup or even an adult dog to adjust to a collar. Choose a collar that fits comfortably but securely (see our sizing chart).  Choke collars are a training aid and should never be used as a substitute for a regular buckle type collar. The collar should have an identification tag and license attached. Simply put the collar on the dog and let him jump, squirm, roll and paw at it if he wishes. Don't encourage the behavior by laughing or trying to soothe him. Do not reprimand him either. It's best to just ignore him and let him get used to it or provide some distraction to get his mind off the collar. Playing, training and eating will work well to get the pup's mind off the collar. Once the dog accepts it, he won't even know it's there. It's similar to a person getting used to wearing a ring or watch for the first time.
