Peruvian sheperd  rides into the sunet on trained mustang Dot while trailing sheep in Upper Gully with the help of border collies in southern Wyoming. Edgar Oscanoa lives at a camp and works alone.<br /> <br /> Sharon O'Toole drove her granddaughter Siobhan Lolly and father George Salisbury around the Ladder Livestock Ranch in southern Wyoming (west of Bags at the Colorado border.) Peruvian shepherds traditionally work at the ranch watching over sheep.  Dot, an adopted mustang that came from the correctional center in Riverside, saved a shepherd's life by finding his way home on a cold night when they were lost.  Nelson, the saved worker, left years ago but the horse is still a favorite among ranch hands like Edgar. He is steady--rock solid--as they guard the sheep.
