Allen had it so bad last winter that he basically had one big open wound on his chin and lost all the fur on his chin. I washed it daily with rubbing alcohol but things made a huge turn-around once I learned its safe to use Stridex pads (those acne cleansing pads made for humans). He cleared up right away once I started using them.

Here my Allen is as it just started to develop - see the black specs?


Here he is last spring as it was finally clearing up -- that looked good compared to what it looked like previously.


At the time, I was certain it would never clear up and that his chin would be sore and pussy forever. It did go away, after persistent cleaning. He hated me for a long time and ran from me when he saw me approaching, but I had to get his chin clean! Now I do periodical chin checks on Allen and only once in a while will I find anything. I swear he knows I check his chin just to make sure it doesn't return bcause he's sooooo sweet and tolerant while I check.
