The most common tactic used by the trainers or pet owners is to challenge their pooch.rnrnLatch a standard retractable leash with a 6-foot leash to your dog's collar.rnrnClutch the leash and toss a ball or treat quite a distance away from you and your leashed dog.rnrnWhen he pulls toward the object, turn and walk in the opposing path.rnrnLet him continue towards it until he can take it as a reward.rnrnAlthough the instructions ask you to use a retractable leash, it is advisable to depend on a regular leash for training purposes.
