Cerebellar Hypoplasia

occurs most frequently in dogs and cats where a portion of the brain called the cerebellum is underdeveloped. Symptoms may be noticed immediately at birth, but become most apparent as the animals try to move and have tremors and generally uncoordinated movement. This occurs because the cerebellum is responsible for controlling fine motor movements. The disease does not usually get better or worse with age, but most animals will learn to compensate for their problems.
