P.S. If you need something for his paws and ears, I found that witch hazel (from the nature store) works in disinfecting his ears - just put witch hazel in cotton balls (not Q-tips) and wipe his ears with it. Then for the paws, I would just dunk his paws on a solution of 1 gallon water to 1 cup hydrogen peroxide and 2 cups vinegar. I would just pour a bit of the solution in a plastic cup deep enough to submerge each paw and use a fresh solution for each paw.
It's a stop-gap thing - just something to clean and disinfect it, not really cure it.
