Today was so cold, that the windshield wiper fluid wouldn't spray.
I had to pull my car over 3 times and clean my windshield with a towel and some Evian water.
It all depends upon the breed of the dog. Ours is a part Husky and she loves lying on the deck out in the cold. When she wants in, she comes to the door and barks. Not sure why the dog mentioned above didn't do the same.
