Details
Ataxia seems to come in breed-related, or breed-specific types. It is characterized by uncoordinated movements, and can have a range of other movement-related symptoms. For this version, two types are described: Spinocerebellar ataxia with myokymia, seizures, or both (SAMS), and Spongy degeneration with cerebellar ataxia 1 (SDCA1). SAMS appears to relate to Russell terrier groups, with an average age of onest of the cerebellar ataxia between 2-6 monts. With the myokymia element, this range goes to 3-8 months. SDCA1 occurs in Belgian Malinois dogs and has an earlier age of onset than SAMS, between 4-13 weeks of age. Affected dogs showed shivering or twitching, and were unable to start walking without falling. Some dogs experience hearing (auditory) changes.
