Canine Eye Registry Foundation - Testing requirements and locations
It is imperitive that you have your dog microchipped BEFORE having any testing done!!!!
Several agencies require it and those that do not are expected to in the future. If you are serious about showing that a chihuahua can be healthy in every area and conform to the AKC standard take the time to have them tested after their first birthday. Microchipping will ensure that there are no questions ever asked as to which dog was tested:) You can find a listing of low cost clinics where they will have independent Canine Orthopedic Specialists, Canine Cardiologists and Canine Opthamologists performing the tests to ensure that your results will have a great impact on our breed. We encourage you to make the investment of your time and money to increase the numbers of cleared dogs on the CHIC registry!!!!
