The next option is called luring. Get down in front of your puppy, holding a treat as a lure. Put the treat right in front of the pup’s nose, then slowly lift the food above his head. He will probably sit as he lifts his head to nibble at the treat. Allow him to eat the treat when his bottom touches the ground. Repeat one or two times with the food lure, then remove the food and use just your empty hand, but continue to reward the puppy after he sits. Once he understands the hand signal to sit, you can begin saying “sit” right before you give the hand signal.
Make the puppy come to you. While he’s on his way to you, still wearing the leash and collar, back up a few paces and then reward him when he gets to you. Continue the progression until your puppy, upon hearing the cue noise, comes to you and walks with you a few paces. Remember that puppies have a short attention span, so keep your sessions short, and end them when your puppy is still eager to do more, not when he’s mentally exhausted.
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.
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.
Help him relax when he comes home. When your puppy gets home, give him a warm hot water bottle and put a ticking clock near his sleeping area. This imitates the heat and heartbeat of his litter mates and will soothe him in his new environment. This may be even more important for a new dog from a busy, loud shelter who's had a rough time early on. Whatever you can do to help him get comfortable in his new home will be good for both of you.
