My mare has been really itchy the last week/s. If I so much as lay a hand on her side, she's making the, "oh my god, it feels so gooood!" face. She has a normal temperature and is only on pasture right now. I'm curious if you think it's an allergic reaction to... something? I have Benadryl and Dexamethosone at my disposal, I'm going to give her the Benadryl and see if it helps, I'm not so ready to give her the Dex just yet. Thoughts?
