I have three piggies, edgar, homer, and clarence. Yesterday when I took the boys out for some outdoors time, I noticed Edgar had a small bald patch on his right thigh (upper thigh towards the butt) Upon closer inspection today, I saw it wasn't inflamed, just pink like a bald piggo. There was some very slight crust, almost like a bit of dryness, and possibly some regrowth of hair. He hasn't lost any weight, and he still eats and isn't lethargic. He isn't scratching any more than usually, and its mostly not over the bald patch. He doesn't seem to be in pain when touched either (he always is fervently against being handled). Any idea what my poor fat boy is going through?
