My poor Teddy isn't get as much exercise as she needs, since I'm undergoing chemo treatments.
Anyway, my daughter put her on the treadmill last weekend and she just loved it. Today she did thirty minutes at a moderate-to-fast walking pace. I don't think it would be safe for her to run since I think her stride might get too long.
She jumps right on when called!
My Teddy really misses the dog park, though.
