Today it is an important research tool for breeders, owners and researchers who want to better understand family relationships and the genetic evolution of the breed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A history built from the archives<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The richness of this database rests on a considerable effort to collect and verify historical pedigrees.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Its managers drew in particular on the old German breeding registers, including archives covering the period from 1918 to 1967, as well as historical French and Dutch documents.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Data from Arthur Muller\u2019s former database were compared against the original registers to correct errors and fill in missing information.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Over time, this documentation has grown through the collaboration of Leonberger clubs, breeders and kennel organizations around the world.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>As of October 11, 2026, the database listed 175,981 Leonbergers.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Behind this impressive number lies a true collective memory of the breed.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Much more than a collection of pedigrees<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the great advantages of the Leonberger Database is that it lets you look beyond names and championship titles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Among other things, you can consult:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The pedigrees and ancestors of many Leonbergers.<\/li>\n\n<li>Genealogical links between different bloodlines.<\/li>\n\n<li>The coefficient of inbreeding (COI).<\/li>\n\n<li>Some documented health results and genetic tests.<\/li>\n\n<li>Test pedigrees to study planned matings.<\/li>\n\n<li>Information on mean kinship (<em>Mean Kinship<\/em>) and genetic diversity.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These tools help us better understand how certain bloodlines appear in today\u2019s population and assess the genealogical consequences of different breeding choices.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A tool for genetic diversity<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In 2018, W.I.L.D. data were used for a major research project by Dr. Pieter Oliehoek on mean kinship and the genetic history of the Leonberger, funded by nine breed clubs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This work helped highlight a fundamental issue: <strong>preserving the genetic diversity of a population is not only about avoiding close matings.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is also necessary to understand how the different bloodlines are represented across the entire breeding population.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A pedigree full of champions can be impressive, but titles alone say nothing about genetic diversity, hereditary health or whether a mating is a good fit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Likewise, a low coefficient of inbreeding does not automatically guarantee a healthier dog.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Genealogy is an essential tool, but it should always be studied alongside health tests, knowledge of the families, temperament and conformity to the standard.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Our reference at Corleone Leonbergers<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>At Corleone Leonbergers, the Worldwide Independent Leonberger Database is our reference for genealogical research and pedigree study.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When we consider a possible breeding pair, we place great importance on the dogs\u2019 origins, their family relationships and the genetic diversity of their bloodlines.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our goal is not simply to produce beautiful Leonbergers or to collect championship titles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We want to help preserve a healthy, balanced breed that conforms to its standard and has as much genetic diversity as possible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Leonberger Database allows us to base our research on international documentation rather than limiting ourselves to the few generations visible on a traditional pedigree.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It does not replace our breeding experience, veterinary examinations or the information we gather from other breeders. It is, however, a fundamental resource in our selection process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">A resource we encourage you to discover<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">We invite enthusiasts, future owners and breeders to explore this remarkable database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding a Leonberger\u2019s origins also means understanding why preserving its genetic diversity is a shared responsibility.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Because good breeding is built not only on the visible qualities of today\u2019s dogs, but also on the decisions that will shape the generations of tomorrow.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Visit the database:<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.leonberger-database.com\/\" target=\"_blank\" rel=\"noopener\">https:\/\/www.leonberger-database.com\/<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Plus de 175 000 Leonbergers document\u00e9s : d\u00e9couvrez la Worldwide Independent Leonberger Database, notre r\u00e9f\u00e9rence pour l&rsquo;\u00e9tude des pedigrees et de la diversit\u00e9 g\u00e9n\u00e9tique.<\/p>","protected":false},"author":1,"featured_media":6393,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"_glsr_average":0,"_glsr_ranking":0,"_glsr_reviews":0,"footnotes":""},"categories":[19],"tags":[],"class_list":["post-6392","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nouvelles-elevage"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Leonberger Database : une m\u00e9moire g\u00e9n\u00e9alogique mondiale au service du Leonberger - Corleone leonberger<\/title>\n<meta name=\"description\" content=\"D\u00e9couvrez Corleone Leonberger, un \u00e9levage familial et responsable de Leonbergers au Qu\u00e9bec.
