Dogs that love to play ball, which as it turns out is most dogs, will be highly motivated to learn how to use an automatic ball launcher, as the opportunity to fetch the launched ball is its own reward. Even a nervous or skittish dog can learn how to operate the ball launcher, although an anxious, nervous, or inexperienced dog may take some more time to get used to the sights and sounds of the automatic ball launcher. Automatic launchers can be adjusted for time, speed, distance and pitch, and they do make some noise. You will need to acclimatize your dog to the machine, and then show him where he needs to stand when it launches, usually next to the machine, a few feet away, to retrieve the ball, and to release the ball into the receptacle at the top of the machine, if you want him to be able to fully operate the automatic ball launcher. An alternative to having your dog reload the machine is to have your dog release the ball to you, and you can reload the machine if you or your dog is not comfortable with him handling the job.
