Stanley's diploma

First of all, I will update you about the contact and obedience course that we took at Hundens hus. We finished it last week. The course eventually was really good for us. As you understand, I am the one that needs to learn new things. Stanley followed the course very good indeed, and I was so surprised to see him zig-zag among the other dogs without interference (it just doesn't happen in the park, you see ;)
We also got a lot's of good advices and good exercises to continue to train on. Finally, our teatcher gave Stanley and me a task to continue to work on after the course: Playing.
She really put her finger on a week spot there. I find it very hard to play with Stanley and that he is hard to get going. It's probably me that is the problem here. Every time I try to play with him, he sort of quits after just a little while and looks bothered. I've tried balls, rope, toys, etc. but I am just not as fun to play with as the dogs in the park.. So - if anyone has any advice when it comes to playing, please write!
