How to Train A Dog to Drop the Tennis Ball
#1: Tell him to drop it, then give him a tug on the leash. When he drops the ball, immediately kick it and let him chase it. Once the dog learns that youre just going to throw it again, he will realize that the faster he drops it, the faster he gets to chase it again.
#2: If the dog wont drop it when you correct him, then put a flat collar on him and then lift him straight up. The dogs head will look straight toward the groun and he will eventually drop the ball, at which point, you should immediately kick the ball and let him chase it again. NEVER ASK THE DOG TO DROP THE BALL AND THEN PUT IT AWAY. When its time to finish the game, fake a throw and then put the ball in your pocket and call the dog to go inside and then feed him dinner.
#3: If you still cant get the ball out of the dogs mouth, then just take the ball in your left hand and beng the dogs lips around his teeth with your right hand. As soon as the dog releases the ball, you guessed it! Throw it, immediately and let him go chase it. Heres the trick: You need perfect timing. As soon as the dog releases the ball (and I mean, that VERY SECOND) you should kick the ball off and let him chase it.
