Can a dog diagnosed with CH be issued a CERF certificate?
Because of its hereditary nature, the policy of CERF is to recommend that any dog with CEA (of any severity) not be bred and affected dogs will not receive a CERF number unless the breed club has not determined CH to be a problem for that particular breed. However, since this is a genetic problem in Tollers and a gene test exists, a dog with CEA can be bred with the assurance disease will not be produced if a normal dog is used in each breeding. Researchers and the HGC are working with CERF and the American College of Veterinary Ophthalmologists to educate them about this new finding in Tollers.
