blind sled dog

Gonzo's owners didn't think he would be able to pull a sled after he started going blind.  But thanks to the dog's pooch brother, Poncho, all is well.  Gonzo and Poncho are hooked up to the back of the sled dogs.  Gonzo depends on Poncho for direction about turns and speed.  He also cocks his head to the side so that he can use his other senses to help guide him.  sled dogs
