About the Leonberger

The Leonberger was created in the town of Leonberg in Germany in the 1840s, reputedly to resemble the lion on the town crest, from Newfoundland, St Bernard and Pyrenean stock. It nearly died out twice in the world wars and was rebuilt from a handful of dogs, which is why the gene pool deserves respect when planning a mating.

Dogs stand about 72 to 80 cm, with a water-resistant double coat in lion-yellow, red, sandy or brown, and a black mask. The standard asks for a self-assured, calm temperament with a willingness to work, and Leonbergers are used in water rescue. A stud should be sound in movement despite the size, and unmistakably steady in temperament.

The Leonberger has two DNA tests specific to the breed for inherited polyneuropathy, LPN1 and LPN2, plus a test for leukoencephalomyelopathy; a serious stud owner will have all three. Add hip and elbow scores and a current eye certificate. Because the breed was rebuilt from few dogs, ask about the coefficient of inbreeding for a proposed mating, and about longevity and cancer in the line.

Health & breeding

We check every hip, elbow, eye and DNA result you give us against the Royal Kennel Club’s public records by hand, and we record who checked it and when. The Royal Kennel Club’s public records may not include all the screening a dog has had, so a dog with no Royal Kennel Club record showing is not necessarily untested.

Health tests for the Leonberger

This panel is Breed Right’s summary of the testing that matters for the breed under The Royal Kennel Club Health Standard. The Health Standard is the Royal Kennel Club’s guidance for breeders, not a registration rule. It describes tests to ask about — it is not a report on any individual dog. The Royal Kennel Club’s public records may not include all the screening a dog has had, so a dog with no Royal Kennel Club record showing is not necessarily untested.

Good Practice — the Royal Kennel Club’s minimum before breeding

The tests the Royal Kennel Club says breeders should, at a minimum, complete before breeding.

TestTypeSchemeWhat’s involved
Hip score (BVA/KC) Screening scheme BVA/KC Total of both hips, 0–106. Lower is better.
Elbow grading (BVA/KC) Screening scheme BVA/KC Grade 0–3. The dog is graded on the worse of the two elbows.
Eye testing (BVA/KC/ISDS) Screening scheme BVA/KC/ISDS Result printed on the eye certificate.
Gonioscopy (BVA/KC/ISDS) Screening scheme BVA/KC/ISDS Grade 1–3 on the certificate; 1 is normal or mild.

Best Practice — further tests it recommends

Completing these as well as the Good Practice tests is what the Royal Kennel Club calls Best Practice.
