Hereditary Ataxia/Spinocerebellar Ataxia
Hereditary ataxia is a degenerative spinal disease affecting spinal cord white matter, central auditory pathways, and peripheral nerves.
Belgian Malinois dogs have been noted to have a variety of movement disorders diagnosed at a young age. While clinically similar, these disease may present with distinct histopathologic lesions with little overlap in genetic sequencing.
