 Carriers and Pets         

What people need to know. Understanding JLPP Carrier and what it means for a pet owner. All breeders, be it Registered or Non Registered breeding dogs should be tested for JLPP. I would like to shed some light on this subject as it seems there is incorrect perceptions in regards to JLPP carriers to you as a perspective puppy buyer. The carrier are ONLY a Carrier of the gene JLPP, They do NOT show signs of the disease nor will they at any stage of their lives, they live out a normal life in every sense of the word.                                                                                       Having a Rottweiler as a pet that is a JLPP carrier only means that it carries the gene and 'may' only pass on the gene if bred from. Pets that come from breeders usually are to be desexed and not breed from if this does not happen and the dog is bred from YOU MUST test the male and female and insure the 2 carries are not mated this will produce an affected litter, mating a carrier to a clear is OK, and it will not produce an affected litter.                                                                                                                                              The thing you need to know if you buy a carrier as a pet the dog will not have a problem in its life from JLPP, you can breathe easy that your pet won't have a problem from JLPP. If you you need to know more on this please email my or have a look at the links proved to help you understand JLPP.

JLPP - Juvenile Laryngeal Paralysis and Polyneuropathy

Understanding JLPP - THE FACTS

There are some breeders of Rottweilers (some registered with ANKC and some not) who will try to tell people looking to buy one of their puppies that Juvenile Laryngeal Paralysis and Polyneuropathy (JLPP) is not a common problem in our breed. We are not hearing of NRC(a) breeders behaving this way, but regardless of this buyers need to be aware of what JLPP is and what to ask the breeder.

We are hearing of breeders who are saying things such as...

“JLPP is no more prevalent in our breed than any other breed.”

FALSE - JLPP only exists in the Rottweiler, Russian Black Terrier and Leonberger.

”Breeders would know if their dogs were JLPP Carriers because they would have seen signs”

FALSE - JLPP Carrier dogs do not exhibit any signs of illness at all. They are a perfectly healthy dog and live a perfectly normal life. It is only when two of these Carrier dogs are mated together that affected puppies can/will be born in a litter.

“Breeders would know if their breeding dogs were Carriers because they have bred
with them previously and all of the puppies were fine”

FALSE - Some breeders do not keep in touch with their puppy people and would not know if they started exhibiting signs of JLPP a month or more after the puppy left. Also given the mode of inheritance of JLPP and the fact that some unborn puppies can die in utero, it is possible that all of the litter ended up being JLPP Clear or Carrier and therefore healthy.

“Educating the public on such diseases in breeds like JLPP is scare mongering”

FALSE - JLPP is real, it exists. We are finding more and more JLPP Carrier dogs becoming apparent within Australia almost every day, as well as around the world. This is a good thing because ethical breeders will use this information to ensure their breeding practises are eliminating any risk at all of producing affected off spring.

“Vets and specialists around Australia say that JLPP is not a problem
in the Rottweiler because it is so rare”

FALSE - Most vets and vet specialists around Australia are still not aware of JLPP. Breeders of Rottweilers are taking this opportunity to educate their vets by way of passing on information to them and encouraging them to find out about this disease.

We cannot express more strongly the importance of asking the breeder you are making inquiries with what the JLPP status of both parents of your puppy is. Insist on seeing the certificates that show this status. Ensure your puppies parents are either both JLPP Clear or only one of them is a JLPP Carrier.

Do not be afraid or embarrassed to walk away from a breeder who will not provide you with the information you are asking to see. There will be another breeder with a lovely puppy who will be
forthcoming with JLPP certificates plus all the required health certificates and clearances you are being advised to ask to see.

JLPP FAQ’s for Rottweiler Breeders

Whilst it is not yet compulsory for Rottweiler breeders in Australia to test their breeding dogs for JLPP, it is envisaged that at least at NRCA level it will eventually become compulsory. It is also envisaged that, as with HD/ED results the dog’s microchip number will need to be positively identified when taking DNA samples for testing. Therefore I highly recommend that rather than taking the swab yourself you take your dog/dogs to a vet for the samples to be taken and microchip number to be verified. This way there can be no question of validity, and also ensures your dog’s results will be on the National database.

Australia currently do not do the tests, labs in other countries currently testing:


Members of the ANKC who enclose a copy / scan of their membership will discount the set price down to £44.00 per JLPP test (down from £48.00). They are also able to test semen samples if an AI has taken place (from a used vial with some semen residue). It is not guaranteed but some results have already been achieved with this, if successful the charge will be an extra £25. Laboklin UK has agreed to a "special" discount for those breeders who wish to test litters. For 3+ puppies the test will be 42 pounds. Updates coming soon for procedure on how to test puppies. 

Note: this lab accepts other swab kits other than just theirs, so you do not need to wait for theirs to be sent to you – just get your vet to use the swab kits they currently have.

OFA website for JLPP testing $65US about $87Aust. 

Note: OFA only accept their swab kits, so there is a wait for these to arrive from the US, some 2-4 weeks at the present time.



Once you get your results back from the laboratory, to add your results to the Australian NRCA Database:
