TESTING FOR GENETIC EYE DISEASES IN DOGSGenetic testing for several inherited canine vision disorders is available to dog owners and breeders. Among the tests available are those for several forms of progressive retinal atrophy, retinal dysplasia, primary lens luxation and cataracts. Unfortunately, not all inherited eye disease in all breeds can be tested for at this time.
Breeders will no longer have to remove affected or carrier dogs from the breeding program. These tests allow for selective breeding to genetically clear dogs, significantly decreasing the risk of producing affected puppies.
Tests are available to breeders, owners, and veterinary specialists. The tests require either a blood sample or a cheek swab. For more information about the tests available, where the individual tests are performed, what samples are necessary, and other new developments refer to the links for the laboratories below.
