I am sure the pug owners will be of more help than I am, but I once saw a show on Sharpeis and it said that when washing a wrinkly dog like that, you have to make sure to wash the wrinkles out very well and dry them totally because mold could grow in there! Ew! I own a Basset Hound and I scrub her winkles well and then towel dry them, and we have never had any skin problems. Also, how often do you bathe Pugsley? Too many baths can dry out the skin and lead to problems. Hope this helps!
