Thanks BlooBabe!! I have some show sheen, I will definitely try that next time I am about there! The mud out here is horrendous. It's thick clay when its wet, and hard as plaster once it dries on them. And thanks to Drifter's aversion to anything he deems "rough brushing", I've had to do my best picking off as much dirt as I can with my fingers.
Thanks also for the cheap substitute for thrush buster! That stuff gets expensive pretty fast. As far as rain rot goes, I have been keeping that at bay so far this season by giving Drifter a maintenance dose of Vit A. It is how we finally cleared up his horrid case of it this summer, and so far it seems to be helping keep it off him. I will keep the listerine in mind for that also! Thanks :)
