Entropian (eyelids rolling inward) and Ectropian (Eyelids rolling
outward) are inherited conditions which require surgical correction.
Both of these conditions disqualify a dog from being shown in AKC
conformation competition.
Progressive Retinal Atrophy (PRA), Central Progressive Retinal Atrophy
(CPRA) and certain types of Cataracts are inherited conditions. Dogs
used for breeding should be examined annually by a Board-certified
Veterinary ophthalmologist, until at least eight years of age, as
hereditary eye problems may not present themselves until later in
life. Dogs examined by a Board-certified Veterinary Ophthalmologist
and found to be free of hereditary eye disease may be registered
annually with the Canine Eye Registry Foundation (CERF).
