Lisa, not sure if you were asking me,,,but Jag's "thing" has always been worse around this time of year,,I've had scrapings done, and they all tend to be some sort of "fungus"..we figure maybe picking it up outside, rolling around???
He doesn't have a thick coat more a working line coat, thin, no undercoat, he never ever gets them on his stomache or legs,,it's always either on the side of his face, his shoulders or back area.
They start out like an eruption,,of pus, oozy nasty crud,,I clip the area down, keep applying the antifungal stuff, within 3-4 days, it scabs over (like road tar! thick black black scab) and for experimental purposes(LOL) I pulled the scab off as within a day,,(one day open oozy, nasty, next day scab) and underneath is clean new skin...fur always grows back..never same spot
