I am retired and have two 50 lb mixed breed dogs--Joy and Scamp. Today on our walk I met some firemen in a school parking lot and Scamp showed them how he could stop, drop and roll. He did it perfectly 3 times with no treats for a reward. I was so proud of him!! I asked if they could use him for demonstrations when they went out to schools to teach children fire safety. They said yes and asked if I could teach him to crawl and to cover his face. So I need your help on both of those tricks. I like to use shaping which is what I used to teach him to roll and to shake. I want to use shaping to teach all of his tricks.
