Wobbler Syndrome (Cervical Spondylomyelopathy)

Wobbler syndrome describes a group of conditions affecting the neck vertebrae and spinal cord in dogs, most often seen in large and giant breeds. The bones, discs, or ligaments in the cervical spine can compress the spinal cord, interfering with the signals that coordinate movement. This compression tends to develop gradually, and the signs can range from subtle changes in gait to more pronounced difficulty walking. Owners often notice an unsteady, wobbly quality to the hind limbs first—a swaying or crossing of the back legs, or a sense that the dog is not quite sure where its feet are. The front limbs may show a stiff or shortened stride. Some dogs appear uncomfortable in the neck, reluctant to lower the head, or slow to rise. The pattern and severity vary, and the progression can be slow or more rapid depending on the underlying cause. This page explores the signals that may suggest spinal cord compression in the neck, the anatomical changes that can produce those signals, the imaging and other investigations used to characterise the problem, and the medical and surgical approaches that exist. The goal is to help you understand what may be happening and what the shape of the conversation with your veterinary team might look like.
