Rain Rot? Now what do we do....

So Alice had a pretty bad case of rain rot when we got her.  So here is what we are doing to clear it up.We are treating her every 3 days with a shampo and a oitment.We are using Horseman's Dream Medicated Aloe Dine 600 Iodine Shampoo with Aloe Vera. The oitment we used was Pierce's All Purpose Nu-stock. The Pierc's All Purpose Nu-stock did not work as well as we wanted it to it worked all right at first but it was alittle to pasty for us to use and we had a hard time washing it out of her coat when it came the 3 days to wash it out.We stopped using the Pierc's All Purpose Nu-stock not because it didnt work well but because it did but it was just to much work to scrub her to get it out witch it kind of irritated her when we did,so we just decided to just use the Horseman's Dream Medicated Aloe Dine 600 Iodine Shampoo with Aloe Vera.
