Canine Yoga Helper?

Took Windy with me running this morning for the first time. It was great, her excited exploration pace is a bit faster than my running speed, and she wouldn't hear of slowing it down. Any time I felt tired I just had to look at her effortless stride and it helped keep me going. Once home I pulled out my yoga mat and started stretching. I was also using a tennis ball as part of one exercise. Windy came in to watch, and once I sat up and she spied the ball, she snatched it up and started tossing it around. For some reason she loves laying on my yoga mat, so during a practice I'm constantly shoving her aside. It's not really a problem, but now my exercise tennis ball is soggy and I have to find a new one. Still, she was so cute attacking the ball I can't really help but smile.
