It does look a bit threadbare and mangy. It may have mange, or it may simply be getting on a bit. My own beard is going white in patches, maybe squirrels do the same? I hope it is not squirrel pox, as spread by grey squirrels. On the squirrel, I mean. Not my beard. I have never been that intimate with a squirrel. Honest.
