Neuroaxonal dystrophy is an inherited neurological disease. Affected dogs typically present between 1-4 months of age with an abnormal gait, hindlimb weakness, and incoordination. The disease rapidly progresses to complete paralysis, blindness, and inability to eat. Affected dogs may also exhibit tremors, loss of hearing, and extension of limbs. Dogs are typically euthanized within a few months of showing clinical signs due to the severity of the disease.
