Cerebellar cortical degeneration (CCD) is a neurodegenerative disease process affecting many dog breeds. The disease affects a specific area of the brain known as the cerebellum. In cerebellar degeneration, the cells within the cerebellum die, causing neurological symptoms in dogs.
The age of onset ranges from neonatal to early onset from weeks to months. Symptoms include walking abnormality, broad stance, swaying, muscle tremors with eating and performing activity, head tilt, loss of coordination and abnormal posture.
