In competition, merely sitting, lying down, or walking on a leash are insufficient. The dog and handler must perform the activities off leash and in a highly stylized and carefully defined manner. For example, on a recall, the dog must come directly to the handler, without sniffing or veering to one side, and must sit straight in front of the handler, not at an angle or off to one side or the other. Training for obedience competitions builds on basic obedience training.
Every dog needs to learn to walk on a leash. Besides the fact that most areas have leash laws, there will be times when keeping your dog on a leash is for his own safety. Learn how to introduce your dog or puppy to the leash, then teach him how to walk properly on the leash, even beside you on a bike. A loose leash walk teaches your dog not to pull or lunge when on the leash, making the experience more enjoyable for both you and your dog.
