We are buggy, but I don’t think that is it. He has a horse fly “boob” on his belly, but we don’t have the little bity gnats, and he isn’t typically bothered by mosquitos. The scabbing just appeared to be kind of stretch marks?
We have had cold weather steady now (highs in the 60’s), and his legs have had no fill for 2 days, so maybe it is a combination of old(er) age and the sudden heat? Supposed to get hot next week (high 80’s), so curious to see what happens.
