Worldwide Independent Leonberger database

16/03/2026

We've switched from http to https (secure connection).
If you have a link to your dog's pedigree, you should check whether it begins with http.
A simple solution is:
1. Add an s after http
2. Or copy the new link and overwrite the old one.

Trial pedihgree doesn't work at the moment, we are trying to fix that a.s.a.p.

Dear Leonberger community,
Unfortunately due to data trawling.we have decided to limit the search options,
From the year 2003 we have collected pedigree data and health results. It soon became clear that taking over names 1 on 1 from the studbooks, caused problems. To make all data more manageable the names needed to be simplified. This meant a huge task for us, because we also had to check and adjust all the ca. 60.000 dogs originating from the Arthur Muller database who gave us this tip in the first place. Our data-set is therefore unique and has copyright!
Because we achieved better management and data control, we were able to deliver the program and our complete database to the Universities of Bern & Minnesota who both still receive quarterly updates.
The database was also the base for 2 reports, 1 published by PHD Anna Letko and 1 by PHD Pieter Oliehoek as well as 2 calculations of Mean Kinship.
We have always felt our data should be easy available to breeders and owners as tool for responsible breeding. Therefore we have never used a log-in or restriction on how many searches a person is allowed to make. We regret that this is now being abused.
Purpose of this rather long epistle is not to find out who is trawling our data but to convince the perpetrator(s) to stop. Please pass on this message!

APPEL aux propriétaires et éleveurs en Belgique: depuis 2020 le studbook Belge n'est plus publié en ligne par le kennelclub. Nous avons demandé au club belge des informations sur les portées nées, afin que nous puissions ajouter les portées dans la base de données indépendante mondiale en vain.
Par conséquent, nous demandons de toute urgence aux éleveurs Belges et aux propriétaires de léonbergs élevés en Belgique de nous envoyer les informations sur le pedigree de leurs portées, c'est-à-dire les chiens. Vous pouvez utiliser le lien sur la base de données ou le formulaire ci-dessous. Les propriétaires peuvent envoyer une copie du pedigree de leur chien à [email protected]
MERCI!
APPEAL to owners and breeders in Belgium: since 2020 the Belgian studbook is no longer published online by the kennelclub. We asked the Belgian club for information about the litters born, so that we could add the litters in the worldwide independent database but to no avail.
Therefore, we urgently ask Belgian breeders and owners of Belgian-bred Leonbergers to send us the pedigree information of their litters, i.e. dogs. You can use the link on the database or the form below. Owners can send a copy of their dog's pedigree to [email protected]
THANK YOU!
OPROEP aan eigenaren en fokkers in België: sinds 2020 wordt het Belgische stamboek niet meer online gepubliceerd door de kennelclub. We vroegen de Belgische club om informatie over de geboren nesten, zodat we de nesten konden toevoegen aan de de database.
Daarom vragen we aan Belgische fokkers en eigenaren van Belgisch gefokte Leonbergers om ons de stamboominformatie van hun nesten, d.w.z. honden, te sturen. U kunt hiervoor de link in de database of onderstaand formulier gebruiken. Eigenaren kunnen een kopie van de stamboom van hun hond sturen naar [email protected]
DANKJEWEL!
