Test Overview:

Ataxia (Norwegian buhund type) is an inherited progressive, early-onset neurological disease affecting Norwegian buhunds. Affected dogs present around 3 to 5 months of age with progressive neurological dysfunction due to nerve cell degeneration in a part of the brain known as the Cerebellum. The cerebellum plays an important role in controlling movement. Clinical signs include uncoordinated movement (ataxia), wide-based stance, high-stepping gait, poor balance, and head tremors. Though the speed of progression is variable, affected dogs are often euthanized due to quality-of-life concerns.
