Casper has come a long way since coming to my kennel. He was very nervous, and not comfortable in harness when I first got him. I took a tip from Roy Smith of Adirondack kennel to try him as a leader. He is now gaining a lot of confidence, and turning out to be one of my best leaders. Well mannered, and a very good dog. Casper is my hardest driving dog. Straight ahead leader, and nothing stops him.
