The trick: Opening a pull door either by grabbing something with mouth and pulling or by using a harness and pulling. Because I've seen Scout pull something fairly easily, I'm thinking this might be something he could easily do that wouldn't be too hard for him. It would also be a big help for us. He's done remarkably well at pulling things he's been attached to look easy. No, he wasn't suppose to pull in any of these situations. He was attached simply because a free hand was needed and he couldn't be free. He got motivated to pull and well the wheelchair, wagon, and sled went along nicely with him. That is what has inspired that maybe he could help with the door situation. I am wondering what would be the best way for him to pull use his teeth or use his harness. Should Scout bite on to rough example a towel and pull using his mouth or should I take a leash around the door handle and hook to his harness and have him pull that way? Any ideas, suggestions, advice greatly appreciated.
