My poor mare has had a hell of a time since arriving from New England to Texas. 48-hours after she got off the commercial hauler trailer, she broke out into hives on one side. Then her eyes started to tear from the flies. Put a fly mask on her (checking it daily), and she ended up rubbing her face. Treated it with vetericyn, cut heal, Silver Sulfadiazine, and swat. We put her on a week of Uniprim just in case. Vet determines it’s a summer sore, and debrides the spot on her face and the spot on her fetlock. I wormed her twice with Ivermectin, and he had me put a mixture of Dex, Swat, and liquid Ivermectin on her spots a couple of times a day. I was able to find a longer flymask that didn’t have any seams across her face (http://www.doversaddlery.com/ultrashield-ex-fly-mask-with-ears/p/X1-23207/ Her face is healing, but I had him check her today again, her fetlock spot got worse because I couldn’t get it covered with a wrap but used AluSpray/AluShield. He debrided it, and covered it while she was a little sedated.
It looks like she’s trying to develop a spot on her stomach now. I wormed her AGAIN today with Ivermectin, and put a layer of the DSI ointment on any scratches I saw. Vet said that some horses are just prone to summer sores, and she might be one of those horses.
I’m getting SO frustrated with this! She’s 16 y/o now, and I’ve owned her for coming 2 years this November. How can I prevent her developing any more sores? She’s otherwise in excellent health and condition. I’ve never dealt with summer sores before, and I lived down south for the majority of my life.
