Similar to humans, dogs that are outdoors in cold weather would have cold noses too. Apart from being active, dogs are curious animals too. Dogs are inclined to roam and when they do they would do a lot of sniffing along the way. Dogs have the inclination to sniff the ground so that the moisture from the grasses will be picked up by the nose. Licking is a normal behavior of dog.

The moisture from the long tongue can be easily transferred to the nose. The coldness of the nose enhances the dog's body temperature regulating system. Dogs have an inefficient temperature regulating system. To regulate body temperature, a dog would open the mouth, hang out the tongue and pant. The fluid that keeps the nose moist and cold aids in regulating body temperature.
