Glossary

Breeder's Option Diagnosis - Result on a CERF exam which indicates the presence of a suspected inherited eye problem, but one that is not causing loss of vision at the time of the examination. A Breeder's Option Diagnosis (BOD) can change, becoming more pronounced and causing the dog to fail a subsequent CERF exam, or it can resolve and no longer be listed on a dog's CERF certificate. Because of this, BOD are allowed to certify, and breeders are urged to consider BOD results along with all other factors when selecting breeding pairs. The general recommendation at this time is to avoid breeding two dogs together who both have a BOD from the same category, or from families that have a history of BOD from the same category.

Genotype - Each dog has a set of genes unique to that animal. The total of each dog's genes is its genotype. This includes dominant genes for traits we can see, and recessive traits that are not seen, but can be passed on to offspring.

OFA - Orthopedic Foundation for Animals. A non-profit organization established in 1966, originally to identify and reduce the incidence of hip dysplasia in all dog breeds. Now operates a database registering results from a wide variety of genetic health screening tests.

Parent Club - The Parent Club for a breed is that club which has been approved by AKC to represent the best interests of that breed. Parent Clubs oversee the development of the breed's official standard, are responsible for educating judges and others on their breed, and hold events exclusively for that breed, such as National Specialty Shows or Field Trials. The Parent Club for the Chesapeake Bay Retriever in the US is the American Chesapeake Club (ACC).

Phenotype - Those traits which we can see, such as height, weight, color, etc. Also, any genetic diseases the dog may develop over its lifetime.
