My mare gets fussy whenever I put her blanket on. She gets fussy, tosses her head, pins her ears back and just gets pissy. If I should be looking into physical issues, what should I consider? Ulcers? Or is this just a quirk? She's perfectly fine when it's on it's just putting it on that she gets like this. I don't think I'm being too rough about putting it on--I just swing it over like normal.
