Oh, ok...I just called and talked to someone at Northwestern cargo and they said not below 10 degrees F. That sounds a little low for dogs, but I don't know

I talked to a live person. I hope that doesn't affect him if it is cold.

don't want a pup-sicle! I am joking, I know this is a serious question. I just can't resist a joke.
Thanks hha.
