Neuropathic disorders in Leonberger dogs:

A variety of neuropathic disorders have been found in dogs and thus in Leonbergers, some of them can best be compared with Charcot-Marie-Tooth in humans, others are Cerebellum Ataxia Leuco Encophalo Myelopathy, Wobbler Syndrome, Degenerative Myleopathy.
A problem is that more or less the same symptoms may be caused by many diseases, included poisoning, hyperthyroism and infections.
In case a dog has a strange gait, has problems to stay on its feet, has his voice changed, has problems breathing, the possibility of a neuropathic disorder must not be overlooked.

Studies of Leonberger Polyneuropathy in Minnesota and Switzerland have resulted in a genetic test for two forms of LPN  lpn 1&2.

Specific information on a form of PN for which a genetic test is available can be found on the
LPN1 page.
