25th Annual Health Registry Introduction

The American Spaniel Club presents to the Fancy the Twenty-fifth Annual Health Registry.  Compiled between these pages are 645 Flushing Spaniels, including 376 in the permanent Registry.  The dogs are listed voluntarily by their owners as normal for one or more of six life threatening defects: cataract (CAT), progressive retinal atrophy (PRA), hip dysplasia (OFA) and/or (PennHIP), Factor 10 (FAC 10), von Willebrands Disease (VWD), and thyroid levels (THY).

The registry lists cataract and PRA certified dogs whose eye examinations were "certified" by a Diplomate of the American College of Veterinary Ophthalmology (ACVO).  There may be a discrepancy in a dog's eligibility for certification due to the individual interpretation of the examining ACVO veterinarian.  Eye exams may not be certifiable due to external eye conditions preventing complete examination of the lenses and retinas.  The eye examination date is listed for cataracts and PRA.  The dog’s Canine Eye Registration Foundation (CERF) number is listed with the cataract and PRA dates, if it was also submitted.
For hip dysplasia, the dog's Orthopedic Foundation for Animals (OFA) number and/or the PennHIP information is listed.  If the PennHIP information is included, it contains the date of the PennHIP evaluation report, the distraction index (DI) for the right and left hips, and the percentile.  The percentile indicates the ranking of the dog’s passive hip laxity (DI) in relation to the breed in the PennHIP database.  For example, a 90 percentile means the dogs hips are tighter than approximately 90% of the dogs in the PennHIP breed database.  Studies show a strong correlation between the distraction index (DI) which represents joint laxity and the predictability of hip dysplasia.  Dogs with low DI values - dogs with tight hips - are less likely to develop hip dysplasia than those dogs with loose hips and higher DI values.  Please note that the PennHIP DI is a measure of hip joint laxity.  It does not allude to a “passing” or “failing” hip score.
For Factor 10, the exact percentage is listed up to 100% and 100+ for dogs over 100%.  For von Willebrands Disease, the exact percentage is listed.
The registry lists thyroid certified dogs whose complete thyroid profile is within the normal range for each of the following:  Total Thyroxine (TT4), Free (unbound) T4 (FT4), T4 Autoantibody, Total Triiodothyronine (TT3), Free (unbound) T3 (FT3), and T3 Autoantibody.  For the thyroid profile, the date of the test is listed.
If a dog is not listed for all defects, it does not preclude this dog is defective for these absent defects.

It must be understood these animals are "certified" clinically (phenotypically) but NOT genetically.  That is, these examinations do not determine carriers of these defects.  In the case of eye examinations and thyroid levels, these tests only indicate freedom from the defects on the date tested and provide no information on the future status of the dog's eyes and thyroid levels.  Therefore, when no current examination results are presented (over one year since date of testing for eyes, and over two years since the date of testing for thyroid levels), we suggest you contact the owner and receive an up to date copy of the eye exam and thyroid levels.
Many cockers develop cataracts before a year of age, but the average age of onset is between two and six years.


* Achieving Permanent Status

Dogs may achieve permanent status for eyes and/or thyroid levels.  Dogs may be entered as permanent for just hip dysplasia, von Willebrands and/or Factor 10, at the owner's request, once said dog turns 8 years old.

Requirements for Permanent Status for Eye Exams

The Permanent Registry contains all dogs that have had a clear eye exam after their 8th birthday.  Dogs who die at 6 years of age are required to have had a clear eye exam after their 6th birthday.  Dogs who die at 7 or 8 years of age are required to have had a clear eye exam within one calendar year of the date of their death.  Breeders are encouraged to continue testing the dogs after they have reached permanent status.

Requirements for Permanent Status for Thyroid Levels


The Permanent Registry contains all dogs that have had a normal thyroid test after their 8th birthday.  Dogs who die at 6 years of age are required to have had a normal thyroid test after their 6th birthday.  Dogs who die at 7 or 8 years of age are required to have had a normal thyroid test after their 6th birthday and within two calendar years of the date of their death.

It is hoped that the Health Registry will be of considerable use to breeders, owners of stud dogs, and purchasers of Cocker Spaniels.  It is an invaluable aid for pedigree studies and the identification of relatively clear ancestral lines.

The Health Registrar has available reprints of the ASC Health Registry's educational releases.  Copies are available for the mailing costs.  This would be an excellent project for individual Specialty Clubs by giving each new member a copy of each release.  The titles of the releases are:

Requirements for Registration of Cocker Spaniels in the ASC Health Registry

How to Hold a Clinic

The Purpose of the ASC Health Registry

Guidelines for Breeding and Purchasing Cocker Spaniels

von Willebrands Disease and Blood Factor X

Skeletal Defects of the Cocker Spaniel
