JUVENILE LARYNGEAL PARALYSIS & POLYNEUROPATHY (LPP) in the Black Russian Terrier
Juvenile laryngeal paralysis and polyneuropathy (LPP) is an autosomal recessive, hereditary disease that affects Black Russian Terriers beginning typically around 3 months of age. Affected dogs have difficulty breathing when excited or exercised and may have a change in their bark. As the disease progresses, they develop weakness and loss of coordination in the hind limbs which will eventually progress to affect the front limbs as well. They may also have difficulties swallowing which can result in choking or pneumonia.
