Also the Tierklinik Kaiserberg writes down some information about tricuspid valve dysplasia:


Tierklinik Kaiserberg: Dysplasien der AV Klappen



A good summary including recommendations for affected breeders you’ll find in the database for genetic disease in dogs (CIDD) of the University of Prince Edward Island, Canada:

A very interesting scientific article from the 'Purina Pro Club'- newsletter from January 2003 as well as an addition from July 2004 you’ll find here:







A study by Andelfinger et al. (2003) can be found here:
