Tonight and tomorrow are supposed to be extremely cold. Not as bad as the Midwest or Canada, but much colder than normal for around here. Ben usually likes cold weather. He gets excited and a little more energetic and he loves to roll in the snow and ice. However, tonight it will be about 6 degrees F. when we go for our evening walk and tomorrow's high is only supposed to be 7F, so it will probably be about 2 degrees when we take him for his morning walk. We don't have a fenced yard, and Ben takes a long time to do his business, especially in the morning, so just standing outside with him is colder than walking down the street. DH and I can put on layers, lots of layers, but Ben has only his fur, and it's not all that thick. (He usually doesn't really get his winter coat until late January or Feb.) How can we tell if it's too much for him? He has been known to stop and turn around when walking in cold rain, so hopefully he will do that if he gets too cold, but I'm wondering how you can tell if a dog is getting hypothermic. Or am I worrying for nothing?
