Clinical features
Affected dogs typically present around 3 months of age with laryngeal paralysis and respiratory distress. Loss of movement coordination often develops a few months to a few years later. Additional symptoms may include limb weakness, ataxia (loss of coordination), progressive muscle atrophy, altered barking (dysphonia), vomiting, and swallowing difficulties. In some cases, symptoms may stabilize, although episodes of ataxia and swallowing difficulties may persist. The dogs of which symptoms stabilize, seem to lead an almost normal life.
