Neonatal Encephalopathy (Poodle Type)

Test Overview:

Neonatal Encephalopathyis an inherited neurologic disease. Affected puppies are smaller than littermates at birth, have difficulty nursing after a few days of life, and often die by 1 week of age. By 3 weeks of age, surviving puppies present with neurologic symptoms including muscle weakness, tremors, inability to walk, wide-based stance and frequent falling. The disease quickly progresses to severe seizures that become non-responsive to treatment. Affected dogs typically die or are euthanized by 7 weeks of age.
