Things you use to prevent hive breakouts on sensitive horses...

So I have your typically skin sensitive OTTB. When it rains, no joke, he breaks out in hives. Spring time is the worst but usually once the rainy season passes we rarely see them. Well this late summer/early fall has been wet around here and of course we had a day of light rain and guess who broke out in hives. So the hives isn’t the big deal, within a day or two they go away, the problem is that his hives turns into scabs that then means he basically loses all his hair. So you can only imagine what this looks like. Usually occurs most on his hind end.

Of course we’re on our way to a rate jumper show this week and he has hair loss, nothing I can do about it now, but does anyone else have this problem? Do you feed anything special to help with this? Any products you spray on them before you turn them out?

I’d love to know. I have tried spraying conditioner on him before turnout hoping it would create a barrier and it seemed to work one day, but haven’t used it long enough to confirm it. He is on a copper supplement (was told great for skin conditions) gets fish oil and has a healthy diet. No health issues other than being sensitive skinned.

My vet wants him to live on prednisone but of course I would prefer not to especially with rated shows.

I feed 8,000 IU natural Vitamin E, flax, and MSM for allergies/inflammation

I sponge off with 1/4 cup white vinegar in a small bucket of water after hosing off sweat/bathing. The vinegar strips the coat of any material that causes his contact allergies. I can’t trust him in turn out in a fly sheet, so if he comes in with hives, usually the vinegar rinse resolves 75% or more of the hives.

I have a vial of dex on hand in case he’s really itchy - I can call the vet and get dosing instructions and give it myself.

Fly sheet, and night turnout if possible. I also have found flax to help my mare who gets hives easily.

Can you share what a “healthy diet” is for your boy?

Ground flax or Omega Horseshine is terrific for preventing skin problems.

Years ago I boarded at a nice place where 90% of the horses had hives or skin problems. Mine included. The barn
only fed Nutrena products. As soon as I moved to another barn I switched to another brand feed and in all the years since, my horse who had been plagued with skin problems has been fine.

Many skin/hair problems are nutrition related. Also vitamin A is very important for skin health.

So for feeding he gets the following in the AM and only grain and aloe in evening:
3lbs of CarbCare Performance
1 scoop of Fish Oil Factor
1 scoop of Mg
1 scoop of 100% pure biotin
1 scoop of 100% copper
1 cup of Aloe Vera
3 flakes of alfalfa

Fish Oil Factor has the following analysis and does contain flax seed: [TABLE]

Just thinking out loud here, maybe if he has a little nick or “opening” on his skin and it rains some bacteria gets in and causes the hives???

Can you keep a light rain sheet on him?

I’ve never had my mare’s hives turn into scabs, so I assume your dude is scratching the bageezus out of them. The diet you described is chock full of things that should help, but it appears they aren’t, so time to up the ante.
When my mare breaks out, she gets a shot of Dex and then Antihistamines (the latter are forbidden substances at rated shows though) twice a day for 5-10 days. We use Hydroxyzine. As soon as he breaks out in hives I’d give him a shot of Dex to prevent him from scratching them and breaking skin. When you don’t have a show coming up, the drug list says antihistamines have a 7 day detection period. Perhaps keep him on antihistamines regularly during the rainy season, and take him off 10 days before a rated show and increase your topical treatments.

Rule on Dex (must be administered by vet):
c. Dexamethasone. This is permitted only for the treatment of acute urticaria (hives). The dose must not exceed 0.5 mg per 100lb (5.0 mg for 1000lb horse) if administered more than 6 hours and less than 12 hours prior to entering the competition ring, and must not exceed 1.0 mg per 100lb (10.0 mg for 1000lb horse) within any 24 hour period.

Topicals, I’ve had good luck with Microtech shampoo and spray, and Not So Sweet Itch spray.

Maybe this would help? Hyderm: Hydrocortisone topical-can’t be used if showing though. It helps with itchies and is mild.

My friends gelding is the same in that every time he breaks out in hives he scabs up and loses his hair. It’s really miserable for them. There must be some kind of bacteria involved as well.

Too hot here for a sheet. We try to keep them in when we know its going to rain a couple days. They go out at night year round. And due to his sensitive skin I would be worried him wearing a sheet could easily turn into rain rot with the humidity we have.

you are describing rainrot…

My guy had some bad hives this summer. Our remedy:

  1. Wash with 2% hydrocortisone shampoo to help calm the skin
  2. Turn out with fly sheet
  3. Feed LungEq (I should have bumped it up to 2 servings/day this year, but I was running out)
  4. Zyrtec will also help a little

My girls has had “hive like” bumps this summer – they have finally gone away. My vet suggested trying Lung Aid, saying he’d seen it work for horses with skin issues. I didn’t end up trying it but may next year if the bumps return.

Its definitely not rain rot, I know what that is as my older gelding use to fight that in the winter. For now sadly, he has lost the hair on his hind end… we’re headed to a jumper classic this weekend he will look fabulous… ah oh well, at least he’s not itchy anymore!

For those of you who feed lung aid, is this show legal do you know?

This… The omega 3’s help boost immunity. Omega Horseshine works wonders for my boy who can also be sensitive to bugs and break out hives. He would also get rain rot in the rainy season. Since putting him on the OHS he’s had no more hives and no more rainrot and no scratches in mud/rain season.

Also forgot to add that feeding Apple Cider Vinegar with mother (has to have the mother) might help. My mare is prone to developing lymphangitis from any tiny little nick on her legs and this has helped a ton.

This. I used to feed a triple dose of it until I got my ponies allergies in order. It helped so much. For the non sweating horse, the simpler and less processed diet the better.

My horse is pretty prone to skin issues and had some skin funk/issues when I got him. I’ve added omega horse shine, corn oil, and he’s also on farrier’s formula, all of which I think have made him super shiny. He’s less prone to getting rain rot now, but occasionally, he’ll still get a bout of hives. This year in Aiken he was a bit of a mess with the sand and needed 3 rounds of IV dex to sort of get it under control. When I’m at home, he’ll get washed or rinsed and then I add a few glugs of apple cider vinegar to a bucket of water and sponge him off with that. That seems to keep the hives at bay.
