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.
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.
It typically takes 4-6 months for a puppy to be fully house trained, but some puppies may take up to a year. Size can be a predictor. For instance, smaller breeds have smaller bladders and higher metabolisms and require more frequent trips outside. Your puppy's previous living conditions are another predictor. You may find that you need to help your puppy break old habits in order to establish more desirable ones.
