scabs all over horses backs??

but rain rot is not a fungus. Its a bacteria.

And yes, pick off those scabs. The rain rot is harboring underneath that. Its a great little environment for the bacteria to live in.

Do you have coolers? Blankets? Anything? If so theres no reason you can't bathe a horse. Give a bath then toss 2 coolers on. The first one will keep them warm while pulling away water. The second one on top will pull the water from the first one so that they dry faster and don't get cold.

At the least wash it with a bucket and sponge in the affected area. If you don't wash it, its not going to go away.

Okay... is there any shampoo that walmart would have that works? I live in a small town and we don't have any tack stores and I don't want to have to wait for an order to arrive online.
I guess I will just wash the infected area. I don't have any coolers, they are pasture kept 24-7..
Once you wash it will it stop it from spreading on the horse more?

hhmm. Atleast get some atibacterial dish soap from there. Wash the area with that. If you can find betadine there (either the soap or solution) add some of that in with the soap too. Pick off those scabs too.

Washing it wont stop it from spreading. It will greatly reduce it though. The rain rot has to be totally gone for it not to spread.

1/2 ORIGINAL liserin(brownish yellow one) with 1/2 water. Not the staight stuff! Put on once a day! And no more rain rot!

Yep, definitley rainscald! If you can get hold of Hibiscrub I would, it's fantastic for everything. It's a seriously hardcore microbial wash which treats everything, I used it for my horses mudfever.

Alright, I'll get that stuff on my horse and get the scabs off. Thanks so much for all your advice!

I use Desitin ointment. I hear some saying not to use ointments but it works. I just rub a bit into the spots and scritch/rub to remove the loose stuff every day or so, reapplying as needed till all gone. I use it on Scratches too. Same kind of stuff. Oh, store brand is just as good. Really helpful when you can't bathe them.

My dog gets little scabs like that in his fur... is that the same kind of thing? Off Topic.. sorry, but I was just wondering. They itch for him a lot...
Thanks to this post I know what rain rot is though! I have never seen it before...

Wouldn't surprise me if it's the same stuff.

Betadine will help! Scrub the area so the scabs are off and cover it in betadine or iodine - you can get either at Walmart.
