You can also lure a down from a sit or stand by holding a treat in your hand to the dog’s nose and slowly bringing it to the floor. Give the treat when the dog’s elbows touch the floor to start. After a few practices, begin bringing your empty hand to the floor and giving the treat AFTER he lies down. When he can reliably follow your hand signal, begin saying “down” as you move your hand.
First, make sure your puppy is comfortable wearing a leash. This can feel strange at first, and some puppies may bite the leash. Give your puppy treats as you put the leash on each time. Then, stand next to your puppy with the leash in a loose loop and give him several treats in a row for standing or sitting next to your leg. Take one step forward and encourage him to follow by giving another treat as he catches up.
Just as a child needs a caring parent; an athletic team needs a coach; your puppy needs a leader and a clear social hierarchy. If you do not take up the role of leader, your dog will; and you will end up with an unruly, disobedient dog. Many people try to win their new puppy's love by letting the puppy always have its way. Buckets of affection is a wonderful thing for most puppies, but it must be tempered with respect.
