Thanks to the dedication and co-operation of many domestic and international Leonberger owners and breeders, our researchers, and the generosity of the LHF and the AKC CHF, we now have a genetic test available for the LPN1 mutation which causes severe, early onset Leonberger polyneuropathy.

Buyer Beware! Be sure to ask to see certification of LPN1 status of the parents of any litter you consider.
