The leg should move forward with the foot low to the ground in a straight column of sup- port. As speed increases, the legs tend to converge more and more to the center line. If a dog’s feet eventually fall on the center

Now let’s look at the action of the rear legs. (Figures 11–20) The rear leg first reaches under the body to strike the ground close to where the front foot is just leaving the ground. (Figures 11–15) During this phase, the thigh and hip muscles do the majority of the work. Next, the leg swings

backward under the dog’s pelvic assembly, using the hip and thigh muscles to generate most of its power. The leg then continues from under the hip toward the rear with a combination of the upper leg and the extension of the rear pastern providing the propelling force.
