Thanks a lot Moonshadow, that's very reassuring and I guess I'll just have be very patient with him

(he's handsome enough, so I think I can handle that, haha)
He was living mostly outside, yes, but when we went to pick him up they had had him in the house for while, and said that they rotated a few of the dogs into the house on different nights.
...our house surely is warmer than it is outside (13 degrees right now, gah!), I should've taken that into account...
