Does anyone think this is OK? He's an inside dog (Lab poss pitbull mix) and all of a sudden tonight he wants to stay out in the yard in 30 degree weather? Nothing else is different, he's eating drinking pees and poops, all the same. Is it OK for him to stay out there? He has no dog house cause he never sayed outside, but I layed down a few old blankets and set his dog bed on top. He ran around the yard for a few minutes wagging his tail, then he just sat looking around, when I went outside he jumped up and we rough housed for a few minute, he went inside had some water and a few bite of kibble then went right back outside! Right know its like 30ish degrees F and evrytime I check on him I find him sleeping on the blankets, he wakes when he hears me and wags his tail hard while looking at me. I try to let him in but he refuses. HELP!
