My 60 lb.er free ranges on my acre and a half fenced property. He has a very nice heated and insulated house he sleeps in in the winter, but in the summer he likes to camp out in an outbuilding that I can close him in securely. The last few nights he has chosen to sleep there, and though the daytime temps are high 70's or even 80's, the night temps drop to 50. He does this for a few nights, and then goes back to his heated apartment. I'd rather let him make his own decisions, mainly because I don't care to carry him the rather long distance back to his house. I would if it got colder. Think we can get away with this from time to time?
