At the end of January 2019, we had to endure the POLAR VOTEX. for a 48 period, we had to deal with temperatures as low as -40 F (actual temperature - not windchill)! Temperatures that cold, require additional precautions to protect against frost bit or worse. This was especially true when taking Watson out for a walk. Yes, we had him wear a coat and booties to protect his feet. Rodger wore multiple layers and ski googles.
Fortunately, the Polar Vortex only lasted a couple of days so the girls were still able to enjoy the snow.
