Canine Wobbler Syndrome

Canine Wobbler Syndrome is a complex health disorder involving cervical spinal cord (part of the spinal cord in the neck area). Breeds most commonly affected are Doberman Pinschers, Great Danes and Beagles.

The spinal column, spine, or backbone in vertebrate animals, is the flexible column extending from neck to tail, and is made of several bones, the vertebrae. The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for many muscles. The cervical (neck) portion of the spinal column consists of seven bones (vertebrae) separated by cartilaginous intervertebral discs, which help absorb shock in motion.

In Wobbler Syndrome, intervertebral discs, ligaments, or bones have some abnormalities or malformations that lead to compression of the spinal cord, resulting in pain, weakness and instability of four legs.

What causes these abnormalities is still uncertain, although nutrition (over-feeding) and hereditary factors are considered to be major contributors to the development of the disease.

Signs of Canine Wobbler Syndrome

Signs may include poor coordination of legs in motion, and awkward swaying movement of the hindquarters. Most affected dogs have difficulty arising. During walking hind legs often cross each other, or in more severe cases, collapse and appear to be rigid.

Treatment of Canine Wobbler Syndrome

Treatment can be conservative or surgical. With mild or moderate signs, administration of corticosteroids usually improves the condition. In severe cases, with acute or chronic intervertebral disc protrusion or extrusion, surgery is often used to decrease the compression of the discs on the spinal cord and the damage of the spinal canal.
