Daisy's DNA profile, issued by the AKC

.

Daisy was recently bred to a dog named Regis, and their litter of puppies was born May 27, 2009, with 3 boys and 2 girls.

Puppies from this union have the potential for field work, obedience, agility, therapy, and conformation. Health has also been a major consideration. Both Daisy and Regis have cleared for hips (OFA good, PennHIP of 90% and 80%), elbows (normal), and thyroid (normal). They have their CERF clearances. And with all those certificates and clearances, both were entered into the CHIC database, of which there are less than 200 vizslas.

.

The breakdown in OFA hip ratings in the 5-generation litter pedigree are:

2 Excellent
17 Normal
26 Good
5 Fair
12 Unknown (non-US dogs)

.

In the 5-generation litter pedigree,there are 144 titles from the AKC, VCA, UKC, NAVHDA, CPE, Delta Dogs, and Therapy Dogs International:

64 Conformation
22 Vizsla Club of America special merit
27 Field
17 Obedience and Rally
7 Agility
6 Therapy and Canine Good Citizen
1 Tracking

Daisy’s Health Records

In addition to her usual annual health checks and vaccinations, there were a number of tests she underwent to determine if she qualified for breeding. These are either required or recommended by the Vizsla Club of America, and the American Kennel Club.

The OFA (Orthopedic Foundation for Animals) test for hip dysplasia has been required by the VCA for decades, and as a result the incidence of dysplasia in the breed has been greatly reduced. The OFA recently started testing for elbows and  thyroid. Daisy scored “good” for the hips (one level below “excellent”, the best score), and “normal” for both the thyroid and elbows.

PennHIP test

.

The PennHIP version of hip x-rays is a recent addition to the arsenal of tests. This determines how tight the hips are, and the likelihood of dysplasia. For Daisy, she scored a 0.3 in the Distraction Index for both left and right hips, good enough to rate at 80% for the vizsla breed. This means her “hips are tighter than approximately 80% of this group of animals”.

vonWillebrand test

.

vonWillebrand is a bleeding disorder more common in other breeds, but can be found in vizslas, so testing is recommended by the VCA. Daisy rated 150%, or normal: “Normal values indicate clear for the vWD trait”.

The CERF eye test certificate

.

CERF stands for Canine Eye Registration Foundation. Breeding dogs can be cleared for phenotypic (apparent) eye disease (as opposed to genotypic, “possible carrier”). CERF exams have to be done yearly. Daisy’s diagnosis: No inherited eye disease found.

Daisy's CHIC certificate

.

The Canine Health Information Center (CHIC) “is a centralized canine health database jointly sponsored by the AKC/Canine Health Foundation (AKC/CHF) and the Orthopedic Foundation for Animals (OFA)…The CHIC database is a tool that collects health information on individual animals from multiple sources. This centralized pool of data is maintained to assist breeders in making more informed breeding choices, and for scientists in conducting research. In order for data to be included in CHIC, test results must be based on scientifically valid diagnostic criteria.”

CHIC issues a CHIC number “when test results are entered into the database satisfying each breed specific requirement, and when the owner of the dog has opted to release the results into the public domain.”

As of April 2009, there were a total of 198 vizslas with CHIC numbers. Two of those vizslas are Regis and Daisy.

Regis’ Health Records

Regis is also entered in the CHIC, OFA, and CERF databases. You may visit his page at his owner/breeder’s kennel website (Paradox Kennel). Here is the listing of his certificates and clearances:
