Unidentified welts

Last night at feeding I noticed some welts on the new mare. The other 2 horses were fine. This morning she had them all over her body. She doesn't seem bothered by them except that she is a little lethargic (but she has been that way since I brought her in last week and I chalk it up to acclimating and/or personality). All three horses are turned out together and eat the same food. Some of the welts are hard. Someone suggested ants but I don't see any evidence. Any ideas? (BTW, one horse just got over strangles - 2 weeks past the outbreak).

I would say something she ate or was introduced to her system since they are not localized as they would be from contact.

They are getting worse?

Years ago my mare has a sudden onset of hives worse than that even & those are pretty bad. Testing showed an allergy to legumes (alfalfa). We fed her only grass hay & put her on allergy shots for a year. She now can eat alfalfa without problems. 8 years later, same thing, that time it was Johnson grass only-again a year of shots & she is again fine.

Your horse could be having an allergic reaction to just about anything. You could try introducing different things & see what she reacts to but testing is much more reliable. They can do initial testing with a blood test.
Azium will clear those hives up quickly but won't get rid of the problem. Listerine baths will help prevent itching to some extent but if left alone those hives can get worse & even start to weep serous fluid & potentially cause a skin infection.
Is her breathing normal?
I would call the previous owners & demand to know if they knew about this problem. She could have been on steroids which have now worn off. I only suggest this because when my mare had her outbreak many people advised me to medicate & sell her. I could never to that to someone else or to my mare.

Just curious, what breed is your mare? Mine is Arabian.

Mls, they got worst from last night to this morning.

Natisha, funny you mentioned alfalfa. I just started feeding her alfalfa cubes as a treat. She is registered with AQHA.

Do you have any dexamethasone on hand?

No, unfortunately.

If you have a solid realtionship with your vet, they should allow you to pick some up. You can orally dose the injectable or use the powdered form on her feed. Liquid is much less $.

Get her cleared up, start at square one and monitor her reactions to everything.

Although a blood panel might not be a bad idea either! Rule out anything funky in her system.

My friends horse got something similar from rolling in nettles.
It looks like an allergic reaction to somthing though.
Did they just come on between the two feedings? Was she is or out when you noticed them?

She is out 24/7.

Well, hopefully that is the problem. With my mare even one tiny leaf of alfalfa was enough to set her off. Now she can eat alfalfa with no episodes. The immune system is a funny thing.
I hope this issues resolves with your mare.
