The owners of the following dogs have graciously allowed us to post their names to help people understand a bit more about the distribution (as far as we know it today) of LP/PN in the Leonberger population. Most importantly, we would like for Leo people to be able to identify if their dogs are related to any of the dogs listed as it is critical to collect blood samples for DNA studies as well as muscle and nerve biopsies (pre- or post-mortem) on as many individuals as possible in order for us to decipher the mode of inheritance and possibly develop a carrier test. All of these dogs had/have various symptoms of a polyneuropathy.

PLEASE NOTE: Not all Leonbergers with symptoms of a neuropathy or of laryngeal paralysis are affected with our Inherited Polyneuropathy.

We also want you to know that this list is not representative of all the the lines in which we have diagnosed Inherited Leonberger Polyneuropathy. In addition, we strongly caution people against the use of this list for breeding purposes until we can better determine how it is passed from one generation to the next, except to say that, at this time, it is unwise to breed a full brother or sister of an affected dog/bitch.

All of the dogs listed below were diagnosed both by clinical signs and by muscle and nerve biopsies, and in several cases by nerve conduction studies. Please email Virginia Bartholomay in order to submit your dog's name to this list.
