So For the 3 years I've been leasing this horse, she's ALWAYS had this (don't know the name if there is one)
But apparently she gets it from laying down. Which she doesn't do often. And it never gets any better or goes away.
I've been thinking about putting MTG on it, or at least cleaning it. She's a little sore when I touch/brush it. More so with brushing.
It's only on her hocks jsyk
