My horse recently came up with a mild case of hives on her flank area. Nothing too crazy - maybe 15 bumps on her right side and 10 bumps on her left. They appear to have gone down in the past day or so. Nothing has changed - same feed, same hay (all of which she is snuffling up as per usual). The weather has gotten drastically warmer and all snow has melted, so she is out on "grass" a couple of hours per day. I don't really have any experience with this - what could cause it? I've owned her for 2 years and haven't had this before. Ideas?

Lord, it could be anything at all. I wouldn't worry about it too much, but pay attention and if it happens again you start collecting clues.

Could be a million and a half things. My horse notoriously gets hives on his sides when he rolls or lays in something that irritates him.

Ditto those.

I keep a bottle of benadryl gel in my first aid kit, which I use for small patches of unidentified hives, bee stings, and similar. It works great, particularly if the irritation is under the saddle area.

Ok - thanks for the info! I have no experience with this so I just needed some reassurance. I knew it wasn't lift threatening lol! I will keep an eye on her and see what happens. How long should it be before they subside?
