The Expertise Centre Genetics of Companion Animals studies which heritable and/or breed-specific diseases occur in the most popular dog breeds, and more specifically, which of these diseases are most common in the Netherlands. More information is available in the Rashondengids (Purebred Dog Guide) published by the National Companion Animals Information Centre (Landelijk InformatieCentrum Gezelschapsdieren, LICG).

The information about diseases in the Rashondengids is updated regularly based on new quantitative research conducted by the Expertise Centre.
