I would like some suggestions as to the best way to treat rain rot now that it is too cold for me to bathe. Our area has recently undergone about two weeks of nonstop rain. Yesterday was our first day of sunshine, I get the horses up and my mare has rain rot worse than I have ever seen...ever. She has always been prone to it, maybe a little patch will show up now and again. I keep MTG on hand to dab on and it goes away...in the summer months I routinely bathe her with a betadine shampoo. This has been working for several years, until now after this unheard of rain. She is literally missing all the hair from her back, most of one side of her face, completely down her hind end and legs, and spots on her neck. I am just at a loss. I feel like if I use the MTG I would end up using the entire bottle in one sitting, it's just so much! Is there something else that can be topically applied that doesn't have to be rinsed? I have heard of homemade concoctions of various types, but I'm nervous about using them because I don't know of anyone personally that has used them. I'm putting some pictures, but they were from when I first got her in. She doesn't look near as bad in the pics as she does now that I have been working on getting the scabs off, but all the hair that you can kind of see matted/laying together, it's all gone now. I can literally rub her with my hand and it just falls out.
