Here is the last step to “Touch”
Take it on the Road:
Practice in every room of your house, backyard, front yard, driveway, park, and pet store. Practice when you have company, when the kids are being loud, any and every distraction that you can use to practice is the best way to have a reliable “Touch”, so no matter what your dog will always come and touch your hand.
Practicing this behavior everywhere you go, will help your dog respond to you in every situation, but if you only practice at home, he will only respond to you at home.
