What to Know About Health Disorder Testing

All dogs have a risk for hereditary health disorders. Testing helps to reduce or eliminate the possibility of our Doodles developing those disorders that can be identified through physical exam, veterinary imaging, and DNA. 

We certify all recommended structural areas through OFA, use multiple DNA laboratories for maximum accuracy, and add additional testing when emerging science shows it may benefit the welfare, healthspan, and lifespan of our dogs.

Our dogs are tested for both structural disorders and DNA disorders before we breed them.

Our litters are DNA tested or cleared by parentage and results are available by the time they are five weeks old.

We test and OFA certify our dogs for structural disorders that are not detectable through DNA. 

We test for the equivalent of OFA CHIC certification (or better) for all the breeds in each of our Doodles' DNA profiles.

Eyes are examined by a board certified veterinary ophthalmologist to confirm the dog is free from ten different hereditary eye disorders. Additional disorders if identified are also recorded. The results are sent to OFA for certification. We retest eyes every year.

Hips are radiographed for signs of hip dysplasia. The radiographs are sent to OFA and evaluated by three board certified veterinary radiologists. OFA passing hip grades are: Excellent, Good, and Fair.

Elbows are radiographed for signs of elbow dysplasia, and sent to OFA for evaluation and certification. 

Patella are examined by our veterinarian for any degree of luxation (abnormal movement) and the results are sent to OFA for certification.

Hearts are examined by a board certified veterinary cardiologist by echocardiogram and the results sent to OFA for certification. Hearts are retested every year by auscultation, and every four years by echocardiogram.

Other Structural Testing is added when advisable for a particular Doodle variety.

Embark Full Panel Parentage & Disorder Testing - 250+ disorders are included in testing at this time. We use this testing to identify and to prevent occurrence of those disorders that are known to affect the breeds in our Doodles' backgrounds.

Embark also provides a genetic COI (Coefficient of Inbreeding). Our goal is a COI of 5% or less, which is generally considered safest for any animal population. We will not breed two dogs where the litter COI is expected to be over 10%, which is where conservation biologists start to see a marked increase in negative health effects.

Wisdom Panel Diversity Score -  Wisdom Panel uses a genetic diversity measurement based on specific markers within our dogs' DNA, known as single nucleotide polymorphisms (SNPs). 

A high Wisdom Panel diversity score is desirable and indicates a wide variety of different genetic traits.

UC Davis VGL CDDY & CDPA Testing - CDDY is a genetic marker that indicates an increased risk for Intervertebral Disc Disease (IVDD). CDDY is common in many smaller dog breeds and can be found in poodles.

We will not pair dogs where any puppy can inherit two copies of CDDY, as research shows that this significantly increases the risk of the dog developing IVDD.

Additionally, by outcrossing to breeds like the Golden Retriever we are able to move toward a goal of eliminating CDDY in our Doodles without sacrificing genetic diversity.

CDPA is a separate marker that identifies a dwarfism mutation in many small dogs. We do not consider CDPA a desirable trait in our Petite Doodles, and we breed away from it.

GenSol NEBL3 Testing - A test identifying a genetic mutation that increases risk of Myxomatous Mitral Valve Disease (MMVD).

Animal Genetics Curl & Furnishings Testing - Not a health disorder issue, but we find these tests helpful in identifying exact coat type in our Doodles.

We believe in full transparency. Our dogs' health disorder testing results are always publicly available regardless of the outcome.

Each of our dogs has a full bio that provides direct links to their test results on sites like OFA and Embark, and copies of their certifications where the testing company does not provide for a direct link.

We welcome questions about any of our breeding decisions, and we are happy to help if you would like referrals to scientific studies or other educational resources about canine health and disorder testing.

Health disorder testing is a cornerstone of any responsible breeder's program, but testing alone isn't enough.

At this time, only a small percentage of known health disorders in dogs are identifiable through testing. As in all mammals, many disorders that are known or suspected to be hereditary, or have a partially hereditary component, remain beyond the ability of today's science to accurately predict before a puppy is born.

This Land Delightful Doodles, with the help of our Doodle families, tracks the lifetime health of our dogs.

After our puppies go to their permanent homes, we send a yearly survey asking our Doodle families to voluntarily provide their dog's veterinary visit results for the prior year - we track and evaluate this information to make breeding decisions that improve the lifespan, healthspan, and welfare of our dogs.

The best and most potent weapon against non-testable health disorders is outcrossing (the breeding of unrelated dogs). Because we are not operating under the restrictions of a closed studbook registry, we are free to seek the best possible matches in both temperament and health for every litter.
