Shaking puppy syndrome is an inherited genetic defect that results in delayed myelination of the central nervous system. This disorder is caused by lack of myelin, which is a white substance that surrounds the axon of nerve cells and has important role in functioning of the nervous system. The disease is a rare neurological disorder that affects dogs of certain breeds. The first clinical symptoms are characterized by a severe tremor, which is usually appearing at twelve days of age followed by late onset convulsions and, under natural conditions, an early death by about 3-4 months of age. Clinical signs of affected puppies may also include difficulties with keeping balance, coordinating movements and maintaining balance in space.
