Of course, all of this depends on the winter climate where you live, so some of these options may not be necessary. However, even if you don't need to worry about snow boots for your Shih Tzu, it's still well worth thinking about the safety issues that could affect you when you're walking your dog at night. You owe it to yourself and to your pup to ensure that you make your walks together as safe as possible, and it's always better to be too prepared than not prepared enough. Your dog will be very grateful!
