I've got an answer (from a vet) on my horse question posted here. It's an allergice reaction to flies and gnats and she's itching (which I already knew) and scratching herself raw. So, she got Dexomethasone, a corticosteriod hormone, to relieve her itching. I'll continue with the soothing shampoos and fly spray. I just hate putting so much fly spray on her in this heat. It's like it's cooking on their skin. Even though I sprayed more on her tonight, the flies were all over her legs. It's awful.
We never really had a winter here so the bugs are in full force. Flies, crickets, gnats... I wish I could swish my pony tail like my horse does!
Thanks for the help and the comments.
