Dog DNA Tests: Top 6 Things Breeders Need to Know


Go to "Dog DNA Tests: Top 6 Things Breeders Need to Know" article

Genetic health testing is growing among breeders who see the benefits of informed breeding decisions and healthier litters. Here are some frequently asked questions about dog DNA tests.

Q: What is genetic health screening?

A: Genetic health screening can provide extremely detailed information to improve your dog’s health, optimize breeding pairs, improve litter outcomes, and contribute to longer lifespans in your breeding lines. Embark is the #1 dog DNA kit that offers the most comprehensive, accurate genetic health test available. One quick cheek swab checks over 230,000 markers across your dog’s genome for variants that may put your dog, or offspring, at risk for disease.

Embark currently screens for 250+ genetic health conditions with an emphasis on breed-relevant conditions, and reports are tailored to your breed. A genetic health screen does not eliminate the need for a veterinary health exam to detect health issues, but it is crucial for detecting genetic defects that could manifest as a disease later in life or could be passed on to offspring if a dog is bred.

Q: How does genetic health testing help me find the right mate for breeding?

A: Just as genetic health testing can help you identify the genetic health of your dog, it can help you make a confident, informed breeding decision. Request that your counterpart screen their dam/sire for health conditions, coefficient of inbreeding, and physical traits. If both dogs are Embark-tested, our genetics specialists can give you projected litter outcomes regarding genetic COI, genetic health condition occurrence, and more. Embark customers also have access to Pair Predictor, an automated Punnet square calculator, in their dashboard for projected genetic health conditions for planned litters.

Q: How does a genetic health test differ from a parentage test?

A: Both are dog DNA tests, but the similarity ends there. Parentage tests are used by registry organizations to determine if the DNA profiles of named sires and dams are consistent with the DNA profiles of offspring listed in their records. They don’t provide information about the dog’s genetic health or genetic diversity. To determine if your dog is predisposed to specific diseases—and may pass them on to offspring—you need a genetic health DNA test.

Q: I already know my dog’s pedigree-based COI. Do I need to check his genetic COI, too?

A: Pedigree-based COI and genetic-based COI scores are not interchangeable—they can vary widely. Pedigrees usually go back 5-10 generations so they can detect recent inbreeding, but they assume the dogs at the beginning of the pedigree are all unrelated, which isn’t an accurate assumption for most dog breeds. Pedigree scores assume all puppies always inherit an even distribution of DNA from both parents across all chromosomes. But in reality, generations of breeding create more randomized outcomes. Factoring genetic COI into your breeding program can help you minimize inbreeding.

Q: Why do I need to test for more than one genetic condition?

A: Often, breeders have just one genetic health condition on their radar. But for many breeds, several genetic health conditions can affect dogs. It’s a best practice to test your dog for all available conditions to ensure disease risk is not passed down your breeding lines, even if the disease is rare in a breed. Doing a “panel” test leaves no stone unturned and lets you identify ‘clear,’  ‘carrier,’ and ‘at-risk’ designations for all breed-relevant conditions.
