Pooches: Dogs & Yoga Mats

I mentioned before how I'm in the midst of training for the Chicago Marathon, and I had high hopes that the pooches would want to run with me. Unfortunately, with the hot and humid summer the dogs have been doing more sleeping than running.
In yet another attempt to foil my training, Miss M has also been hijacking my yoga mat. Every time I unfurl the mat for my after-run stretch, I turn around to this:
I think there is something about the spongy material that she just really likes. Needless to say, she is quite stubborn and it's really hard to move her off. She also thinks when I'm lying on the ground stretching, this is the perfect time to sit on me.
I have made some modifications and started to use her as a type of "yoga brick"; since my legs are so tight I can barely touch the floor, so it's nice to have her for balance when I attempt to touch the ground.
I think a yoga mat would actually be a good "bed" for dogs who might chew a regular bed, or have accidents in their crate. It would be really easy to wipe down, and still provide padding. I tested it out in Miss M's bed, and she sprung right in so she could lay on it. She still refused to move:At the same time, I've seen her practicing her moves around the house: "Downward Dog"Probably so she could pretend she's a natural on the mat:
