Man Spots A Dog In The Middle Of Nowhere But When It Won’t Budge, He Ends Up Discovering So Much More

Sled Dogs

There is yet another job that dog has been able to help out with. Well, sled dogs have always been used to explore terrains that are impossible to cross. These dogs are sent on the first expeditions to the north and south poles as well as Antarctica where it is impossible for humans to travel.  In Alaska, sled dogs were used to deliver medications and supplies to the far-off towns.
