Holy moly!! That is impressive!!! Only with a border I bet. lol. Now THAT is distance work.
A woman in my agility class uses a scooter. It's been amazing to watch her and her service dog. Which, btw, wasn't officially a service dog to begin with. She was a pet. But when things got bad, she did some crash course training and now her pet is also her service dog. Agility is her "play/down time". And she loves it. Now, THEY need distance work, but that's only because the dog is used to working so closely to her. It's awesome to watch when both dog and handler have a great night. (they did last night. did better than me and koji).
I need to do some training. I'm thinking I'll use our round coffee table. It's something I can do while I'm at home, watching tv, etc.
