What Is IVDD in Dogs?

I had two Coton De tulears that were diagnosed with IVDD when they were 18 months old, I thought I would do a piece on it as I often get asked:

What Is IVDD in Dogs?

Intervertebral Disc Disease (IVDD) in dogs is a neurological condition that involves the spinal cord, the vertebrae, or back bones. (the small, round bones that make up the spinal column or spine), and the disc material between each vertebra.

The vertebrae protect the spinal cord and the nerves that transmit impulses to and from the brain and the rest of the body. The spine also supports the weight and movement of the body. When something is wrong with the spine, it causes pain or even immobility. In between each vertebra is a soft, jelly-like disc surrounded by thick fibrous tissue. This intervertebral material serves as a cushion to absorb shock and help provide flexibility to the body as it moves.

IVDD in dogs is a condition that occurs when the cushioning discs between the bones of the spinal column either bulge or burst into the space containing the spinal cord. When this disc material pushes on the spinal cord, it can cause pain, nerve damage, and even paralysis. This condition is also known as a slipped disc, herniated disc, or bulging disc.

Certain dog breeds that have a long back and short legs, including Dachshund, Basset Hound, Shih Tzu, French Bulldog, Lhasa Apso, Pekingese, and Beagle, are predisposed to IVDD. The disease has also been known to occur in large-breed dogs, such as German Shepherds, because with age disc degeneration occurs.
