This can't be said enough, but really shouldn't have to be said at all. Take care of your animals during times of extreme weather.
How long could you stand to be shut up in a car, windows rolled up, on a 90-degree day? Or on a winter day like today, think about your dog, who is chained up outside. The snow is piling up around his doghouse, which is not insulated from the bitter wind. His dish of water has turned to ice and the food you gave him this morning is now frozen.
Your animals are your responsibility. They are counting on you to protect them. Don't let them down.
