Passive range of motion – The aim is for the joint to pass through flexion and extension. This is a good exercise to improve your dog’s joint health, mobilising your dog’s joint through its natural range of motion improves joint nutrition, local blood supply increases, reduces swelling and lymphatic fluid and prevents stiffening of the joint. N.B. you can perform this exercise standing up, however much easier for you and your dog if they are laying down.
Extension:
One hand above and one hand below the hock joint but supporting the limb, gradually draw the two apart to increase the joint and open the hock to an extension.
Flexion: opposite as above, and you can flex the above joint (stifle/knee) to increase the joint flexion
