1st 2 years when winter hit and when it got below 25 I brought him in the garage, he loved it, in a nice carry light with straw beeding, after a couple of weeks this year he would hunker back in his outdoor house in the kennel, I would reach in and make him come in, finally after feeling that he was warm to the touch I just let him stay, I would call but he does not want to come inside, I freshen the water, check the feed, but he likes it out there, I did build his house with 1/2" rigid foam board insulation then plywood, but door is open, anyone else dog love it outside in the cold?
