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.
First, teach the release word. Choose which word you will use, such as “OK” or “free.” Stand with your puppy in a sit or a stand, toss a treat on the floor, and say your word as he steps forward to get the treat. Repeat this a couple of times until you can say the word first and then toss the treat AFTER he begins to move. This teaches the dog that the release cue means to move your feet.
You can teach your puppy at home and I'll help you. My puppy training book is called Respect Training for Puppies: 30 Seconds to a Calm, Polite, Well-Behaved Puppy. I'll show you my proven step-by-step training schedule for teaching your puppy all the words he needs to know, plus consistent household rules and routines, housebreaking, crate training, acceptance of being handled, calmness, gentleness, and general obedience training.
Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
Take it outside. Finally, you’re ready to test your puppy’s skills in the Great Outdoors. There will be new challenges with this step because all the sounds, smells, and sights your puppy encounters will be intriguing and new to him. Be patient and keep the first walks short. While you’re on a walk, if your puppy looks as if he’s about to lunge toward something or is about to get distracted (you’ll notice this because you will keep your eyes on him at all times), make your cue sound and move a few steps away. Then reward him with a treat for following you.
Imagine your puppy running out the front door. You call him, waving a treat. But he'd rather chase a squirrel into the road than come back to munch on a treat. In addition to the obvious danger of Puppy getting hit by a car, he learns that he doesn't have to listen to you. He learns that he's in charge of what he decides to do and what he decides not to do.
