It’s dog flu season, so Xi Shi will be protecting her immune system, in part, by wearing her new coat and boots. Don't be too quick to laugh at doggie boots because dogs lose heat through their feet so let's keep those little paws warm.
Canine Influenza was identified by the Center for Disease Control in 2005. So it is a relatively new influenza, a serious problem for dogs only, not transferable to their humans.
