Hi, I've never posted in this part of the forum before, guess there's a first time for everything.
Anyway, my Solid Paint Bred gelding Dallas has developed some hives on his lower stomach area, below his flanks. I haven't recently changed his feed so I don't think that's it. I'm thinking maybe it was a bug bite, as his old owner had this happen from bug bites one spring/summer(I'm in MA so we're getting bugs and plants back by now). I'm keeping a close eye on them and plan to call my vet my on Friday if they get bigger/spread or haven't changed. They don't seem to bother him too much, they're more itchy than anything.
Anyone have an idea what it could be caused by or anything I can do to help him?
P.S. I can take pictures tomorrow if that would help, although they're somewhat hard to see since he's black.
