Observe the animal weight bearing and seated Let the animal wander around the consult room and observe the animal from all sides/angles and observe whether the animal moves with ease or difficulty. Pay attention to: weight bearing (digits should spread evenly), joint angles, conformation, symmetry, stance abnormalities, muscle atrophy and gross abnormalities. 2.

There is increased vertical displacement of the hindquarter on the lame limb side. Spinal sway can be seen in dogs with bilateral hip dysplasia. • Be aware of neurological conditions that may present as orthopaedic conditions e.g. ataxia, reduced proprioception, dragging feet. 3.
