How much excercise does a Dane need?
A Great Dane needs only a moderate amount of exercise. This amount is less than breeds such as German Sheperd Dogs, Dobermans, Dalmations, and the other active sporting and herding breeds. Usually a walk on a long lead (then they get more exercise than you do by running from here to there smelling everything) or 10 – 15 minutes of chasing a ball, frisbee, or stick per day are sufficient. Of course the more the better. However, it is recommended that you do NOT jog with a Great Dane until they are at least 18 months old (they grow so much so fast that continued strain of this kind could lead to development problems).
