strange how that stuff works. My grandmother was allergic, Mom is not, and I am. When I would get it as a kid Mom put me in the bath and :shock: used a scrub brush and a bar of lye soap. Once she broke the blisters and scrubbed me with the lye soap...it cleared up. I really wouldn't recommed this today....the lye soap really burned. Years later when she moved, Mom found that old bar of lye soap and asked if I wanted it. Ummmm...NO THANK YOU!!! I still have enough vivid memories of those baths.
You do, however, need to clean the dogs collars and anything else that they have come into contact with.
(If nothing else...someone got a chuckle out of this I'm sure.)
