Cardiac Data Collection!


The LHFI is launching a major survey of cardiac health in the Leonberger breed, in preparation for a future international research project. We are currently seeking information from anyone who owns or has previously owned a Leonberger suspected of having any heart condition, including cases of sudden death. 
All information submitted will be treated in the strictest confidence and no details of owners or individual dogs will be released into the public domain. Registered identities of individual dogs will be kept confidential within the scope of this research, to be used for pedigree analysis and associated purposes. 

Please email to to receive a Data Submission Form.

International Leonberger Health Survey 2019!

The survey was sponsored by Leonberger Health Foundation.

The Leonberger Health Foundation International is a nonprofit charitable foundation formed at the turn of the 21st Century by members of the Leonberger Club of America’s Health, Education, and Research Committee to facilitate the solicitation and distribution of donations given to support health related breed-specific research. The LHFI considers breed health, longevity, and preservation to be significant challenges that need to be actively addressed by the world wide Leonberger community.  Since 2000, over $300,000.00 has been raised and distributed to researchers in several countries.


Over the past several months, the LCGB health committee has been working with the health and research team at the Kennel Club to draw up a Breed Health and Conservation Plan for our Leos. This involved a very thorough process that included a comprehensive literature and research review, as well as a thorough review of results compiled  from both British and international leonberger health surveys spanning many years. This was done as part of a broad initiative launched by the KC a few years ago, the aim of which is to "ensure that all health concerns are identified through evidence-based criteria, and that breeders are provided with useful information and resources to support them in making balanced breeding decisions that make health a priority."
