Canine Eye Registration Foundation (CERF)

Eye CERF was founded by a group of concerned purebred owner/breeders with a goal of eliminating heritable eye diseases in purebred dogs through registration, research, and education.

CERF is dedicated to educating the public on matters involving canine eye disease. It provides a variety of reports to help educate owner/breeder on heritable eye disease questions, healthy breeding stock, and breed-specific eye problems.

The Genetics Committee of the American College of Veterinary Ophthalmologists lists Lens Luxation and Cataracts in its Occular Disorders Presumed to be Inherited in Purebred Dogs for the Jack Russell Terrier.

Occurance of a defect can not be anticipated in a given terrier, and the age of onset of the disorder(s) varies from quite early (less than one year of age) to several years of age. The JRTCA Breeder's Committee is urging terrier owners to have their Jack Russell's CERF tested yearly. Don't be fooled into waiting for a symptom of an eye problem. Many times there are none. Early detection and reporting is important to the future of the Jack Russell Terrier.
