Duke was a four year old Doberman pinscher, weighing twenty three kilos. He was not only faithful, but also intelligent, understanding, loving and helpful. Duke showed skill and patience that was hard to imagine. Once while jumping, Duke hit Chuck above the belt causing him to fight to keep his balance. Duke knew instantly that something was wrong with his master and he never jumped on him again. Duke knew when he had to pull and how much. With Hooper standing, the dog walked to the end of the leash and tugged steadily. Leaning against the pull,
Hooper learned to keep his balance. Duke helped Hooper to go on for short walks. Thus, if it wasnt for Dukes support, Hooper would never have been able to walk on his legs again
