Does anyone know of a reputable site that sells Derma-clens in the 14 oz containers? My vet only has 1 oz tubes and gave me the impression that it dosn't come in the bigger containers anymore. Looking on line it appears that Zoetis spun off fro Pfizer, and they still show the 14 oz. I have an injured pony and the 1 oz tubes aren't going to last long.
