Today I noticed my gelding has what appears to be hives on him. I first noticed small, multiple bumps on his neck yesterday - not really visible but I could feel them when I rubbed him (rice sized).
Today they are more noticable - some are dime sized and now I see them on the side of his belly.
He seems otherwise fine...I will call the vet in the a.m. I'm sure she will say to treat him with benadryl...
Anyone have any comments or experience with this?
