Neonatal cerebellar Ataxia is an early onset, inherited neurologic disease affecting Coton de Tulears. Symptoms present shortly after birth when normal littermates develop coordinated movement. In affected dogs the Cerebellum does not function properly and pups do not develop the balance necessary to stand or walk normally. Affected puppies tend to scoot on their stomachs to move and often fall to their side and paddle their legs. These pups usually develop tremors as well. While the disease does not appear to progress in severity after 4 months of age, puppies are usually euthanized due to a poor quality of life.
