What is the white stuff on cross country horse's legs?
So I've been LOVING watching cross-country on YouTube lately! Today, I was watching the great Quimbo (isn't he gorgeous???) and his rider, Andrew Nicholson, on their 2013 Rolex cross-country course. I noticed some white stuff slathered on his legs and I've seen it on other horses, too. What is this white "stuff?" What does it do? Is it good or bad? Is it only used for cross-country? Thanks!!
