Dog DNA tests compared

For a mixed breed, a DNA test tells you which breed risks to read up on. For any dog, it can flag variants that change medication choices and screening. Here is what to expect and which test to pick.

What a test gives you

  • Breed ancestry. Percentages by breed, useful for mixed breeds because breed sets lifespan and disease risk. Look up each breed found on the breed pages.
  • Genetic health variants. Hundreds of known mutations. The ones that most often change care: MDR1 (drug sensitivity in herding breeds; affects which parasite, chemotherapy and sedation drugs are safe), degenerative myelopathy risk, progressive retinal atrophy variants, von Willebrand disease (bleeding risk before surgery), exercise-induced collapse, and breed-specific ones such as dilated cardiomyopathy variants in Dobermans.
  • Traits and predicted adult size. Coat, size, and for puppies a size estimate to compare with the growth calculator.
  • Genetic age or diversity scores. Interesting, not actionable.

What it cannot do

Diagnose disease. Most conditions that shorten a dog's life (cancer, heart valve disease, arthritis, kidney disease) are polygenic or environmental and have no single test. A "clear" health panel does not mean a healthy dog; a flagged variant does not mean a sick one. Bring the report to your vet and turn it into a screening plan.

Tests to compare

Both companies use cheek swabs, return results in a few weeks, and offer vet consultation on notable results. Prices change; check both.

Frequently asked questions

Are dog DNA tests accurate?

Breed identification from the major companies is accurate for breeds in their reference panels, especially for the largest contributors in a mix; small percentages are less reliable. Health variant testing is a laboratory genotype and is accurate for the specific variant, but a variant is a risk, not a diagnosis: many carriers never develop the disease.

Which dog DNA test is best?

Embark and Wisdom Panel are the two established options with large reference databases and health screening. Embark is generally rated higher on health reporting and vet follow-up; Wisdom Panel is often cheaper. Both beat the cheap kits with small panels.

Should I DNA test a purebred dog?

For health, yes, if the breed has known variants: MDR1 drug sensitivity, degenerative myelopathy, PRA, von Willebrand, exercise-induced collapse. Knowing a dog is MDR1-affected changes which drugs it can safely receive. For breed identity, no.

Can a DNA test predict how long my dog will live?

Not directly. It can flag variants for life-shortening conditions and, in mixed breeds, tell you which breeds' risks apply. Combine the result with the breed pages here and your vet's screening plan.
