Mist is my 9 or 10 year old TB mare. She has hives again this year. I'm pretty convinced it's some kind of plant that she's allergic to or something. She only gets it in the warmer months, and she's gotten it every year so far that we've had her. I have no idea where to even start looking, though! None of our other horses have ever gotten hives before that I know of. I'll be watching Jazz (Mist's daughter) to see if she gets them, too, but she hasn't shown anything, yet.
Anybody else ever had this problem?
