Teach him on your ob. He knows the command to come back to you...So long leash (we have a 50 m. leash for this)and any correction type what works, call him when almost on the end of your leash, if not coming correct him. He is a good boy coming back to you, the greatest when he is next to you,then reward him.
Tennis net and things like that (bicycle thrown before the dog, guy jumping before the dog etc), are thought to be very old fashioned methods, when not around a dog will go through your command of coming back.
The basic of the exercise is come to you when called, and get that guy when told. So coming back when he is not called is bad boy, turning around when not called is a bad boy, going to the decoy when called is a bad boy. Coming when called is a good boy, going in a straight line when not called is a good boy etc.
