Haopee, she is food driven. I don't think she'd do anything for a toy. I do give her a treat after she puts the jacket on. She seems to get through that part okay now. But, the minute I let her free, she goes crazy.
I've pulled back a little. The sessions were starting to traumatize her, so I've gone back to jackets for walks but not around the house. I think I need a new strategy. I thought after a week she would start to accept the jacket. It seems it's only made her more stressed out about them. In fact, a couple of days, she was hiding on my mom's lap when I called her to go for the walk. She was beginning to associate walking with jackets and trying to avoid both.
To answer your question, no, I've never did any mini-agility courses with Misha. That might be something to explore.
