　●Snow nose(Snow nose)

The phenomenon of nose fading in winter is called snow nose, which is a seasonal reduction of nasal pigment. The weather is low in winter, and the nose plane is the part with the lowest body temperature, causing the color of the nose plane to become lighter. It often occurs in huskies, golden retrievers, Labradors, etc. In this case, usually not all the nasal plane will turn white, and the lips, foot pads, eyelids, paws and skin will not turn white.
