The most significant clinical sign of the disorder is cerebellar ataxia; affected dogs often also display myokymia, an involuntary quivering of a group of muscles or part of a single muscle, seizures, or both. As the disease progresses, the muscle quivering or mykymia can reach a point that dogs can overheat; seizures can also become progressively more severe.

How is this condition treated?
There is no treatment for this disorder. Certain medications may be prescribed to control symptoms.
What actions should I take if my dog is affected?
