Your girls are so adorable and gorgeous.
My girls, Bella and Lina, don't like to go outside for walks when it's cold, wet, or snowing. We don't walk them when the weather is freezing or below freezing (and it gets very cold with lots of snow during winter here in Illinois). We don't want the girls to get frost bite on their paws or ears. They are trained to go on pee pads during inclement and cold weather, and they love it (spoiled rotten).
