have a hound that every summer seems to develop a red looking rash on body, hound is a lemon & white and just looks "dirty", think some used sodium iodide for sores on legs. Any other ideas or remedies? I've got some "old" methods for mange etc but this is not mange.

get some prolate-lintox from feed stoes.use as directed.i get same thing.on some dogs.it is same ingredients as paramite from vets.
