One thing that is the same all around the world
Having a Swissy is to have a great four legged friend that makes your life better.  - Inga Britt

The vision for the GSSHWWDB (Grosser Schweizer Sennehunde World Wide Database) began in 1998 as a collaborative effort between Swissy fanciers Jonathan Bastian (USA) and Dr. Wolfgang Reese (Germany). The goal was  to compile pedigree and health data on Greater Swiss Mountain Dogs in America and throughout Europe. Over years of data entry, the database has grown to over 47,000 dogs worldwide.


In 2021, the decision was made to form a 501(c)3 organization and move forward with the process of making the database available to everyone throughout the GSMD community. Our all volunteer board of directors has over a century of experience in the breed.


The database includes health and pedigree information which has been collected through extensive research, voluntary submissions from supporters, as well as imported data from The Orthopedic Foundation for Animals (OFA). The database can serve as an important tool for those seeking information, studying pedigrees, assessing health in particular lines, and making breeding decisions.


GSSHWWDB seeks the international support of owners, breeders, affiliates and fanciers throughout the globe to help continually update information and supply photo images. Our goal is to be as accurate as possible with data, and we realize that errors and inaccuracies may occur. We have attempted to maintain the integrity of the submitted information through verification of original documentation and official registries. Any updates received will be validated. Reported erroneous or inaccurate information contained within the database will also be confirmed prior to making changes. Corrections will be made in as timely a manner as possible.


It is our hope that this information serves the Greater Swiss Mountain Dog community and through these efforts, more informed breeding decisions can improve the health of our beloved breed.
