DNA testing has become one of the most powerful tools available to responsible dog breeders. A simple cheek swab can reveal whether your dog carries genes for over 270 hereditary diseases—information that was impossible to obtain just a decade ago. This guide covers everything you need to know about genetic testing before breeding, including what tests to get, which providers offer the best value, and how to interpret your results.
- DNA testing identifies carriers of genetic diseases before they produce affected puppies
- Most genetic diseases are recessive—two healthy-looking carriers can produce sick puppies
- Testing costs $85-$200 per dog and can be done at any age, even on puppies
- Results from major providers (Embark, Wisdom Panel, Paw Print Genetics) are accepted by OFA
- Never breed two carriers of the same recessive condition together
What is Canine Genetic Testing?
Genetic testing analyzes your dog’s DNA to identify mutations linked to inherited diseases, coat color traits, and breed ancestry. Unlike physical health tests that examine your dog’s current condition (like hip x-rays or cardiac exams), DNA testing reveals what’s hidden in the genetic code—including whether your dog carries disease-causing mutations that could be passed to offspring.
The technology works by extracting DNA from cells collected via a cheek swab, then scanning for specific genetic markers associated with known diseases. Modern testing panels can screen for hundreds of conditions simultaneously, making comprehensive genetic screening more accessible and affordable than ever.
DNA Testing vs. Health Clearances: DNA testing is one component of comprehensive health testing. Breeders should also complete OFA certifications for hips, elbows, eyes, and heart. For the full picture, see our complete health testing guide.
Why DNA Testing is Non-Negotiable Before Breeding
Skipping genetic testing is one of the biggest mistakes a breeder can make. Here’s why DNA testing should be completed on every breeding dog:
Carriers Look Completely Healthy
The majority of genetic diseases in dogs follow an autosomal recessive inheritance pattern. This means a dog can carry one copy of a disease-causing mutation and appear completely normal. These carriers show no symptoms whatsoever—you cannot identify them through physical examination, behavior, or any other observable means.
The problem arises when two carriers are bred together. Statistically, 25% of their puppies will inherit two copies of the mutation and develop the disease. Without DNA testing, breeders unknowingly produce affected puppies generation after generation.
Real Example: Degenerative Myelopathy (DM) affects German Shepherds, causing progressive paralysis. A carrier shows no signs of the disease and can live a full, healthy life. But breeding two carriers together produces puppies that will lose the ability to walk—typically by age 8-10.
Preventing Heartbreak and Financial Loss
Producing puppies with genetic diseases creates devastating situations for everyone involved. Families bond with puppies only to watch them suffer from preventable conditions. Breeders face the emotional toll of producing sick animals, potential legal liability, refund demands, and reputation damage. A single $150 DNA test can prevent thousands of dollars in veterinary bills and immeasurable heartache.
Building Buyer Confidence
Puppy buyers are increasingly educated about genetic health. Many specifically seek out breeders who provide DNA test results. Sharing your dogs’ genetic status demonstrates transparency and professionalism. It also provides documentation that protects you if disputes arise later.
Improving Your Breeding Program
DNA testing gives you data to make informed breeding decisions. You can strategically pair dogs to avoid producing affected puppies while still using valuable dogs that happen to carry certain mutations. Over time, genetic testing helps breeders reduce disease frequency in their lines without losing genetic diversity.
What Does a DNA Test Screen For?
Genetic Disease Variants
Comprehensive DNA panels screen for hundreds of genetic conditions across multiple categories:
- Neurological conditions: Degenerative Myelopathy, Exercise-Induced Collapse, NCL
- Eye diseases: Progressive Retinal Atrophy (multiple forms), Collie Eye Anomaly
- Blood disorders: Von Willebrand Disease, Factor VII Deficiency
- Cardiac conditions: Dilated Cardiomyopathy (DCM) genetic markers
- Musculoskeletal: Centronuclear Myopathy, Muscular Dystrophy
- Metabolic disorders: Hyperuricosuria, Cystinuria
- Drug sensitivities: MDR1 (sensitivity to ivermectin and other drugs)
Carrier Status
For each tested condition, your dog will receive one of three results:
| Result | Genetic Status | Breeding Implications |
|---|---|---|
| Clear | No copies of the mutation | Safe to breed; cannot pass the mutation to offspring |
| Carrier | One copy of the mutation | Can breed only to clear dogs; 50% of puppies will be carriers |
| At-Risk/Affected | Two copies of the mutation | Will likely develop the condition; breeding not recommended |
Coefficient of Inbreeding (COI)
Some testing providers calculate your dog’s genetic Coefficient of Inbreeding (gCOI)—a measure of how related the dog’s parents were. High inbreeding increases the risk of inherited diseases and reduces overall health. The gCOI is more accurate than pedigree-based calculations because it measures actual genetic relatedness rather than relying on paper records.
Coat Color and Traits
DNA tests can predict coat color genetics, helping breeders understand what colors puppies might produce. This includes testing for dilute genes, merle patterns, and other traits. While not health-related, this information helps breeders plan litters and avoid problematic combinations (like double merle breeding).
Double Merle Warning: Breeding two merle dogs together can produce “double merle” puppies with serious vision and hearing defects. DNA testing identifies merle carriers even when the pattern isn’t visually obvious (cryptic merle).
When to Test Your Dog
DNA testing can be done at any age—the genetic code doesn’t change throughout life. Many breeders test puppies at 8 weeks to identify breeding prospects early. However, most breeders test adult dogs before making breeding decisions.
Request DNA test results from the breeder or test the puppy yourself before committing to a breeding program.
Know your female’s genetic status so you can properly evaluate potential breeding partners.
Results typically take 2-4 weeks. Test early to avoid delays when your female comes into heat.
Some breeders test entire litters to provide documentation for puppy buyers.

How to Choose the Right DNA Test
Consider Your Breed
Different breeds have different genetic disease risks. A Labrador Retriever needs testing for Exercise-Induced Collapse and Centronuclear Myopathy, while a Cavalier King Charles Spaniel needs cardiac-focused genetic markers. Check your breed club’s recommended testing protocol to ensure you’re testing for relevant conditions.
Check OFA/CHIC Requirements
If you’re pursuing CHIC certification, verify that your chosen provider’s results can be submitted to the OFA database. All major providers listed above are OFA-accepted, but confirm specific tests are eligible for your breed’s CHIC requirements.
Compare Features vs. Price
If you primarily need basic health screening, a budget-friendly option like UC Davis VGL or Animal Genetics may suffice. If you want breeding tools, COI calculations, and puppy buyer reports, Embark or Optimal Selection provide better value despite higher prices.
Turnaround Time
Standard results take 2-4 weeks. If timing is critical (your female is coming into heat soon), GenSol’s 24-48 hour turnaround may be worth the premium.
Understanding Your DNA Test Results
When you receive results, you’ll see each tested condition listed with your dog’s genetic status. Here’s how to interpret and act on the information:
All Clear Results
If your dog tests clear for all conditions, they won’t pass any of the tested mutations to offspring. This dog can be bred to any partner regardless of that partner’s carrier status (for those specific conditions).
Carrier Results
A carrier result is not disqualifying—many excellent breeding dogs carry mutations for one or more conditions. The key is making smart pairing decisions:
- Breed carriers only to clear dogs for that specific condition
- Accept that 50% of puppies will be carriers (this is fine—they’ll be healthy)
- Document carrier status transparently for puppy buyers
- Consider the dog’s other qualities—carriers with excellent structure, temperament, and health can still be valuable breeding animals
Never Breed Carrier to Carrier: When both parents carry the same recessive mutation, 25% of puppies will be affected. This applies even if both dogs appear completely healthy.
At-Risk/Affected Results
Dogs testing “at-risk” or “affected” have two copies of a disease-causing mutation. These dogs will likely develop the condition (for recessive diseases) or already have it. Generally, affected dogs should not be bred, as all puppies would be at least carriers.
Frequently Asked Questions
Comprehensive DNA panels range from $85-$200 depending on the provider and number of conditions tested. Individual tests from UC Davis VGL start around $40-$85. Bulk orders of 4+ tests typically receive 15-25% discounts.
Most providers deliver results in 2-4 weeks from when your sample arrives at their laboratory. GenSol Diagnostics offers expedited 24-48 hour turnaround. Plan ahead and test before you need the results for a breeding decision.
Yes, carriers can be bred responsibly—but only to dogs that are clear for that specific condition. This ensures no puppies will be affected. Eliminating all carriers from breeding programs would drastically reduce genetic diversity, which causes its own health problems.
Embark for Breeders offers the most comprehensive feature set with COI calculations, breeding tools, and OFA integration. Paw Print Genetics excels for breeders wanting genetic counseling support. UC Davis VGL is best for budget-conscious breeders testing specific conditions. Choose based on your specific needs and budget.
Yes, all major providers (Embark, Wisdom Panel/Optimal Selection, Paw Print Genetics, UC Davis VGL, Animal Genetics, GenSol, Orivet) are OFA-recognized laboratories. Their results can be submitted to OFA’s database and count toward CHIC certification for applicable conditions.
COI measures how genetically related a dog’s parents were. Higher COI indicates more inbreeding, which increases the risk of inherited diseases and reduces overall health. Genetic COI (calculated from DNA) is more accurate than pedigree-based COI. Embark provides this metric; aim for COI under 25% for healthier puppies.
Yes. Both the male and female should be tested before breeding. Even if a stud dog claims to be tested, request documentation and verify results. This protects you from producing affected puppies if the other owner’s records are inaccurate or incomplete.
