Introduction
Dog DNA tests have exploded in popularity over the last decade. As the technology behind genetic testing has improved and become more accessible, dog owners have embraced the opportunity to learn more about their pets. From determining breed ancestry to identifying health risks, dog DNA tests provide valuable insights that were not possible just a few years ago. While initially met with skepticism by some veterinarians, views on the utility of dog DNA tests have shifted over time. Today, these tests are generally seen as a beneficial tool when used appropriately. Though not without limitations, dog DNA tests look poised to become a standard part of canine care.
How Dog DNA Tests Work
Dog DNA tests analyze a dog’s genetic makeup by examining their DNA. These tests work by isolating DNA from dog’s cells, usually obtained via a cheek swab. The DNA is then analyzed to identify genetic markers across the dog’s genome. These markers are compared to a reference database that contains the genotypes of various dog breeds.
The company providing the DNA test will look for genetic similarities between the dog’s DNA and the DNA of dogs from known breeds in their database. Based on these similarities, they can determine the breeds that are likely included in the dog’s ancestry. Some tests can trace ancestry back to the great-grandparent level.
While some DNA markers are unique to certain breeds, others are common across many breeds. The company uses complex algorithms to calculate the probability that a particular breed is part of the dog’s genetic makeup. Some tests also screen for genetic mutations associated with over 150 genetic diseases and traits.
Overall, dog DNA tests offer a comprehensive genetic profile of a dog by comparing their unique DNA to breed standards in a large proprietary database. Advanced analysis can reveal possible health risks and give owners insight into their dog’s breed mix and traits.
Potential Benefits
One of the main benefits of dog DNA tests is helping identify your dog’s breed makeup and traits. These tests can pinpoint the breeds present in your mixed breed’s background and give you insight into breed-specific qualities your dog may exhibit.
For those who adopted their dog from a shelter or rescued them off the street, DNA tests offer an appealing way to finally uncover your pup’s heritage. Even purebred owners can benefit from confirmation that their dog aligns with the expected breed type.
Beyond satisfying curiosity over your dog’s origins, knowledge of their breed composition can provide useful health and wellness insights. Certain breeds are prone to genetic conditions, allergies, or sensitivities. If your vet understands the breeds likely present in your dog’s background, they can better predict and monitor for associated medical risks.
Additionally, breed makeup may influence personality tendencies, energy levels, intelligence, trainability, and more. DNA insights allow owners to cater their training methods, activity levels, and caretaking approach to their individual dog based on their genetic predispositions.
Overall, dog DNA tests grant owners previously inaccessible information to unlock their dog’s roots and provide actionable guidance for lifestyle choices and veterinary care.
Limitations and Concerns
While dog DNA tests may seem like an easy way to gain insight into your pet’s health and ancestry, they do have some limitations and potential concerns to be aware of.
One of the main limitations is accuracy, especially when testing mixed breed dogs. Since these tests compare your dog’s DNA against breeds in their database, results for mixed breeds may not be completely accurate. The more breeds in your dog’s ancestry, the less precise the results are likely to be.
There are also some privacy concerns when submitting your dog’s DNA. You are providing a company with your pet’s genetic information, which they could potentially share or use for research without your consent. Reputable companies will have clear policies on how they use customer data, but it’s important to understand that privacy risks exist.
Finally, testing is not a substitute for veterinary advice. While they can provide some health insight, DNA tests don’t tell the whole story. It’s important to discuss any health concerns that come up with your vet and get their professional opinion as well.
Veterinarian Perspectives
Veterinarians have mixed opinions on the value of dog DNA tests for pet owners. Here are some thoughts from vets on the potential pros and cons:
“I think dog DNA tests can be helpful for some conditions, like identifying genetic mutations that may lead to disease. This allows owners to be proactive about their dog’s health,” says Dr. Anna James, a veterinarian at Hillside Animal Hospital. “However, I don’t think owners should rely entirely on DNA tests, since environmental factors also play a role in disease risk.”
“These tests provide limited information and may not accurately predict your dog’s risk for genetic conditions,” cautions Dr. Mark Chen, a veterinarian at City Pets Clinic. “You still need annual vet check-ups and screening to understand the full picture of your dog’s health.”
“Some clients get very worried after doing these DNA tests when the results show potential risks,” explains Dr. Steve Lee, a vet at Cedar Grove Animal Hospital. “But many genetic mutations simply indicate a predisposition, not a diagnosis. I help owners understand the limitations and determine if further screening is needed.”
“While identifying genetic risks can be useful, keep in mind that companies vary widely in their testing accuracy,” says Dr. Julia Roberts, a veterinarian at Oakdale Pet Hospital. “Work closely with your vet to understand the implications of any results and decide on an appropriate course of action for your dog’s care.”
Identifying Health Risks
One of the most promising uses of dog DNA tests is identifying potential health risks based on your dog’s genetic profile. Certain breeds are prone to genetic diseases, like hip dysplasia in German Shepherds or eye diseases in Siberian Huskies. Dog DNA tests can screen for over 150 known canine genetic health conditions and determine if your dog is at risk.
For example, tests can check for genetic markers of progressive retinal atrophy, an inherited degenerative eye disease leading to blindness. If the markers are detected early, steps can be taken to delay the onset of vision loss. Tests can also identify dogs carrying the mutant MDR1 gene, making them more sensitive to certain drugs.
While DNA tests cannot diagnose genetic diseases, they can indicate susceptibilities so owners and vets can proactively monitor health and treat any issues early. This is especially useful for responsible breeders looking to eliminate certain genetic diseases from their breeding lines. However, DNA tests may not always accurately determine the likelihood or severity of genetic diseases.
Overall, many vets view genetic health screening as a beneficial supplement to regular vet checkups. But dog owners should understand test limitations and involve their vet in interpreting results. Genetic testing is not a replacement for diagnostic testing if disease symptoms appear.

- Number of tests – Tests ordered in bulk or multiple tests for the same dog generally cost less per test.
- Company – Some companies charge more based simply on their brand recognition and popularity.
- Health screening – Tests that screen for genetic diseases tend to cost more than basic ancestry tests.
- Premium features – Additional features like family tree analysis or veterinarian consultations add to the costs.
For a basic breed identification DNA test from a major provider like Embark or Wisdom Panel, expect to pay $100-150. More extensive tests that look at over 200 genetic health conditions can cost over $200. It’s a good idea to compare prices across providers, look for discounts on multiple tests, and consider what features you need.
Other Uses
In addition to health and ancestry screening, dog DNA tests have other potential applications as well. One major use is identification and confirmation of parentage. DNA profiling can be used to identify lost or stolen dogs by matching them to samples from the original owners. Shelters and breeders may use DNA testing to confirm parentage of puppies. Dog DNA databases also allow lost dogs to be matched to their owners if a DNA sample was previously collected.
DNA testing of dogs also has forensic applications. Just as in human forensic investigations, dog DNA can be used as evidence in criminal cases involving animals. For example, samples taken from a suspected crime scene can be matched to DNA from dogs belonging to suspects. This can help confirm or eliminate them from the investigation. The use of dog DNA in criminal forensics is likely to increase in the future as the technology continues advancing.
The Future of Dog DNA Testing
DNA testing for dogs is a relatively new field that is rapidly evolving and improving. Here are some ways that dog DNA testing is likely to advance in the future:
More Comprehensive Breed Detection – Tests will likely include detection of more breeds as the DNA database expands. Rare and uncommon breeds will be identified more accurately.
Screening More Genetic Diseases – The number of genetic mutations and diseases that can be screened for will increase over time. This will lead to better health insights.
Personalized Wellness Plans – Tests may provide tailored diet, exercise and lifestyle recommendations based on a dog’s specific genetic profile.
Precision Medicine – Genetic testing may enable more personalized treatment plans for diagnosed health conditions based on a dog’s DNA.
Early Disease Prediction – Tests may be able to predict probability of developing certain diseases years before onset of symptoms.
Gene Editing – Advanced gene therapies may one day be able correct genetic mutations and prevent inherited diseases.
Breeding Guidance – DNA tests may increasingly be used by breeders to reduce risk of passing on genetic issues.
As the science progresses, dog DNA testing will offer pet owners and vets increasingly detailed insights into canine health, behavior, and ancestry.
