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].
