The Great Pyrenees Club of America is a participant in the OFA's CHIC program, and encourages all breeders to health test their dogs.

To view results of tests submitted for a particular dog, visit and enter the dog's registration number or registered name into the search field. By further selecting the dog's name you an also view results for related dogs [Parents, Offspring, Full and Half Siblings].

Though not part of the CHIC program for Great Pyrenees, the following tests are also available ~

     ~ Addison's Disease

     ~ Degenerative Myelopathy [Test not considered definitive at this time]

Additional Genetic Research Projects ~

     ~ The Dwarf Project

         In 2007 veterinarians from UC Davis began researching the gene mutation responsible for                Dwarfism in Great Pyrenees. Research is ongoing. No test is currently available.


OFA/CHIC maintains a database of DNA samples, available to approved veterinarians and universities, to aid in genetic research. Breeders and owners are encouraged to submit samples to the CHIC DNA Repository.
