our neighbors across the hall have a tiny dog, it's furry but less than a year old, and it's been barking on the front porch we share for an hour straight. i think it's cold! it's maybe 40 degrees right now, but it's going to get even colder. SO tried knocking on their door, but no one is answering. i had him open the door so it could get in the hallway to warm up, i'm afraid it's gonna die of hypothermia. how cold is too cold to leave a small dog outside for hours at a time or overnight? i've never had a dog, maybe i'm being irrational and they're hardier than i think. should i put it back outside? it doesn't even have a dog bed or a blanket our there
