It is important to understand that canine locomotion occurs as a result of the summation of all of the joints. If one of the joints does not move correctly, other joints must adapt their movement to correct the body’s movement as a whole. The dog’s gait may not appear to have changed if these joint movement adaptations are minimal. As the changes and adaptations increase an unsoundness will become evident. It is important in the canine athlete and working dog to identify these alterations as soon as possible.
