All purebred dogs are more or less inbred, which comes with inherent health risks. That is especially true for large breeds. However, Leonbergers, especially those bred in North America, are fortunate compared to other large breeds. The Leonberger breed standard does not call for traits that can be detrimental to health. The precise and restrictive breeding regulations of the Leonberger Club of America (LCA) and other Leonberger clubs, and the work of the Leonberger Health Foundation International or LHFI, have resulted in Leonbergers being relatively free of inherited illnesses compared to other large dog breeds in America. For more information see Humane Society Veterinary Medical Association, “Guide to Congenital and Heritable Disorders in Dogs,” rev. 2011
The Leonberger Health Foundation International (LHFI) was founded in 2000 by Waltraut Zieher and other members of the LCA’s health, education, and research committee to “facilitate the solicitation and distribution of donations given to support health related breed-specific research.” The LHFI also administers a program that collects DNA samples from Leonbergers to share with universities and research institutions.
LHFI’s global biobank contains DNA samples from more than nine thousand Leonbergers. Among the organization’s notable achievements are the eradication of Addison’s disease among Leonbergers and the raising of nearly half a million dollars for research into conditions that affect canine health, including osteosarcoma, hemangiosarcoma, glaucoma, cardiac diseases, thyroid diseases, and neurological disorders. Its research also supports healthful longevity and aging as well as population diversity. Another success is the fact that since 2011, no Leonbergers with two copies of the LPN1 gene mutation (which causes Leonberger polyneuropathy) have been recorded in LHFI’s biobank.
One happy event for our family was when Bronco received his Grey Muzzle Award, which is an award given for longevity by LHFI. LHFI bestows the award on any Leonberger who has reached the age of twelve. These Leonbergers are the canine equivalents of centenarians, humans who are at least one hundred years old. The Grey Muzzle Award is also given to breeders, because they are partially responsible for the dogs’ longevity. The Grey Muzzle Award was certainly a happy event in Wikman family. If you have a twelve-year-old Leonberger, simply fill out a form on the LHFI website or send an email to email@example.com.
The foundation will ask for some information, including the registered name and call name of the dog; the breeder’s name, kennel name, address, and email; the dam’s registered name; the sire’s registered name; the owner’s name, address, and email; the birth date of the dog; and whether the dog is alive or dead. If the latter, they will want to know the cause of death. In addition, they would like you to write a one-paragraph tribute to the dog and send two (preferably high-resolution) photos—one head shot and one favorite photo.

I can add that when Bronco passed away, we sent his DNA to the University of Minnesota to be used in research. This was facilitated by the LHFI.
