CHIC (Canine Health Information Center)

The Canine Health Information Center, or CHIC, maintains a database of health screening tests for individual dog breeds. The Norwich Terrier parent club selected three health screening tests considered meaningful when selecting breeding stock with the goal of producing healthy puppies. Each dog that has completed the three tests is assigned a CHIC number. This does not mean that the dog with a CHIC number has passed the screening tests. It only means the dog has taken the tests and the results were submitted to CHIC.

The CHIC requirements for the Norwich Terrier include:

  • Eyes, a CERF evaluation
  • Hip Dysplasia, either OFA evaluation or PennHIP evaluation
  • Patellar Luxation, OFA evaluation

As of September 2010, there were approximately 200 Norwich Terriers listed as having CHIC numbers on the OFA website. This means test results for these dogs have been submitted for OFA Hips, OFA Patella, and CERF.
Looking at these particular tests separately on the OFA website, there are 498 Hip entries, 379 Patella entries, and 343 CERF entries.
Hip results taken from total submissions (570) from 2007 to 2010 that include those not made public, show the majority of Norwich Terriers fall into the category of “Good” with 56.1% of the total submissions; 23% “Fair”; 7.2% “Excellent”. 13% fell into the “Abnormal” category, including 0.4% “Borderline”; 9.8% “Mild”; 3% “Moderate”; 0.2% “Severe”.
Patella results taken from total submissions from 1998 to 2010, 388 submissions, show 96.4% normal and 3.6% abnormal.
I encourage members to participate more in submitting Patellar Luxation results. It is a simple and inexpensive exam. No x-rays, no drugs, just a simple manipulation by the veterinarian. Because test results are totally dependent on the ability of the veterinarian to evaluate patellar luxation accurately, I suggest members have a vet qualified in orthopedics perform the evaluation. Considering how simple and inexpensive it is, members should be participating more in this simple OFA exam. We can only learn and make good decisions by having information.
I also encourage more members to participate in having their dogs’ eyes tested. CERF clinics are held routinely at many dog shows. Breeding stock is recommended to be evaluated annually. An inherited disease such as juvenile cataracts can show up as late as 5 years of age.
OFA testing for hips is getting more convenient for breeders. No longer is anesthesia needed. In some areas, mobile OFA health testing to include hips and patellar luxation is offered at dog shows.
I want to thank the membership for participating in health testing and completing and submitting the specific tests NTCA recommends for CHIC participation. The numbers continue to increase each quarter. It is very encouraging!
