JLPP DISEASE IN ROTTWEILERS

 
 

THIS IS NOT CURABLE IF YOU GET AN AFFECTED ROTTWEILER WITH JLPP

WE GUARANTEE YOUR PUPPY WILL NOT BE AFFECTED

 


Juvenile laryngeal paralysis and polyneuropathy (JLPP) is an autosomal recessive, hereditary disease. Autosomal recessive is a disorder that means two copies of an abnormalo gene must e present for the disease or trait to develope.

This affects Rottweilers 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.

One major sign is difficulties swallowing which can result in choking or pneumonia. Another sign is the dog looks like it has kennel cough.

Test Results


Normal This dog has tested normal (or clear) for the mutation known to cause JLPP. It can only transmit a normal gene to offspring, and can be bred to a dog with any test result without risk of producing affected offspring.

Carrier This dog has tested as a carrier for the mutation known to cause JLPP. There is no evidence at present that these dogs will develop clinical symptoms of JLPP. It may transmit either a normal gene or a mutated gene to potential offspring.

Affected/At-Risk This dog has tested as affected for the mutation known to cause JLPP. It is at risk for developing clinical symptoms of JLPP, which generally begin to appear at about 3 months of age. The clinical signs include difficulty breathing, change in bark, weakness and loss of coordination, and difficulty swallowing which can result in choking or pneumonia. There is no effective treatment for this condition, and even with supportive nursing care, these dogs do not live more than a few months after clinical signs begin.




The brain controls muscles through signals that travel through nerves. A disease that affects the nerves is called a polyneuropathy. Due to a quirk in the way an embryo develops, one of the longest nerves in the body supplies the muscles of the voice box (larynx). The vocal folds vibrate as air moves over them allowing a dog to bark. When the dog breathes in, muscles in the larynx pull the vocal folds aside so that air can move easily into their lungs. If nerves are unable to convey that message properly, the muscles become weak or paralyzed. The longest nerves are often affected first; hence laryngeal paralysis is the first symptom. The vocal folds cannot be pulled out of the way as the dog breaths in. They vibrate noisily and can obstruct the flow of air into the lungs particularly when exercised or hot. The dog may also choke on their food or water or regurgitate, which can result in pneumonia.
