Intervertebral Disc Disease (IVDD)

Chondrodystrophy (CDDY) and Intervertebral Disc Disease (IVDD) Risk

Chondrodystrophy (CDDY) is a hereditary skeletal condition associated with shortened limbs and premature degeneration of the intervertebral discs. These early changes in the spinal discs significantly increase a dog’s lifetime risk of developing Intervertebral Disc Disease (IVDD).

Dogs carrying the CDDY mutation are more likely to experience:

• Disc calcification
• Disc herniation (slipped disc)
• Sudden back pain
• Reduced mobility or hind-leg weakness

In severe cases: paralysis

The CDDY + CDPA panel helps breeders and owners understand a dog’s genetic predisposition to these spinal issues, supporting informed breeding decisions and proactive health management.
