Cerebellar Ataxia (Finnish hound type) is a progressive, early onset, inherited disease affecting dogs. Symptoms are usually present by three months of age and progress quickly. Affected dogs have marked degeneration of the Cerebellum which causes ataxia. These dogs have difficulty controlling leg movements and keeping their balance. Changes to the cerebellum can usually be identified via MRI. Ataxia eventually limits the dog’s ability to eat and affected dogs are often euthanized.
