after i am done riding my horse, i give him a bath. so i rinse him off, then i take some betadine & put that on a curry comb with very small teeth. i scrub the areas where my horse has rain rot very well with that. after, rinse it off & i make sure i dry him EVERYWHERE suuuuper well. i then take scratch cream and put it on all the areas and he is good to go! just make sure you dry him very well. this worked wonders for my horse.
Hi Alyssa, talk to your vet about ailments like this.
