Here's a picture of my new contact trainer that Rick built for me. It's just an 8 foot aluminum plank topped with wood. He put a hinge on the end of it and we attached it to the existing doghouse. Now I can reward the up contact easily with a "yes" and they can get their treat right away as I can just throw it on top of the flat roof. Also, this makes it easy for Quila and Gromit to turn around and go back down right away. I was finding it was difficult to reward my golden for "ups" on the normal 12 foot DW, as she would have to continue all the way across the entire length before she could just stop and try again. I just LOVE this!
