Denali is 7 years old. His owner thought he was getting too old to run in a fast sprint team. This dog has done the Open North American!!!!!! This boy has many years left. He used to do 40 or 50 miles. He is extremely thin. I would love to see this boy go to a skijor home where he can live inside, put on some weight and be loved. He is very very friendly. A calm friendliness. He would love to go for long hikes. He is a sweety.
