I went to the store and bought some sidewalk chalk. You can't just buy a couple pieces, so I ended up with a 16 piece pack, so I'll be able to do this test MANY times in the future!
I decided to use neon green so it would really show up, and I colored the entire bottom side of Lilly's hoof. I walked her around outside on the concrete for about 5 minutes, doing some circles and some turns. I have to admit, I thought more of the chalk would be gone after all that walking, so I'm not sure if the sidewalk chalk is maybe too thick for the test? Or maybe it worked just like it was supposed to!
I did the left front first and then went back and did her right front just to see if there was a big difference between the two. Here are the results:
|Left front before...|
|Left front after...|
|Right front before...|
|Right front after...|
