Have you ever wondered what breeds make up your mixed breed dog? Now there is a simple affordable blood test available, which can show your dog’s family tree as far back as their Great Grandparents. Knowing your dog’s genetic makeup can help you understand his or her behavior, and assist your veterinarian with disease awareness. Unfortunately certain breeds are more susceptible to certain eye, heart, and joint problems, but these conditions can often times be managed if detected early. The database was designed using 10,000 samples collected from pure bred dogs all over Australia. The ADVANCE DNA test can detect up to 200 different breeds, including the Australian Dingo. Surprisingly, 50% of the Australian Dog population is composed of cross bred dogs, which is higher than any other developed country in the world. Your results will include a family tree extending back three generations, along with a chapter about each breed, and a page highlighting any diseases of importance for those breeds. There is also an option for a second test to see if your dog actually carries the genes associated with those diseases. You can access real life examples at www.advancepet.com.au.

By Kaitlyn Wells FYI We’ve updated the availability and pricing for picks in this guide, added to our FAQ section, and provided more-current information about the accuracy of each kit. If your pup’s parentage is perplexing, a dog DNA test could reveal its ancestry. These tests use your dog’s saliva (and the thousands of DNA markers within it) to tell you which breeds make up its family tree. We dug into 17 products, consulted five genetics experts, and collected slobber from five dogs to find that Embark Breed + Health Kit’s sizable breed database, wide array of inherited-disease screenings, and reliable customer support mark it as the best dog DNA test. Embark has a comprehensive breed database, screens for more genetic diseases than its rivals, and has reliable customer service. Embark’s breed database covers most dogs recognized by the American Kennel Club, as well as some street dogs and the gray wolf. The company says its breed results are 95% to 99% accurate. And Embark analyzes twice as many genetic markers as the competition, leading to more-accurate results, our experts say. The genetic-disease detection tool screens for 210 mutations, more than any kit we tested. Yet there’s no government oversight of the industry, so the genetic tests aren’t independently verified. Still, we appreciate Embark’s policy of contacting pet owners about worrisome results, which the competitors did not do. The website is easy to navigate and features a shareable dashboard and downloadable report, so sharing results is seamless. Wisdom Panel Premium identifies more AKC-registered breeds than any kit we tested. Also, it’s cheaper, and the turnaround time is quicker than with other kits. But Wisdom Panel uses fewer genetic markers in its tests than the competition, so we don’t think the results are as accurate. *At the time of publishing, the price was $160. The Wisdom Panel Premium kit is the best option if you have a mixed-breed dog who’s suspected to be of a breed uncommon in the United States. This service tests for more than 350 different breeds, including the coyote, the Mexican street dog, and the wolf. However, Wisdom Panel analyzes fewer DNA markers in your pet’s saliva than Embark, so we don’t think the results are as accurate overall. (Over the years, Wisdom Panel has refined its accuracy claims—both as the science evolves and to attract customers. In 2019, it claimed a 93% accuracy rate; in 2021 it stopped disclosing its rate; and in 2022 it claimed a 98% accuracy rate.) Wisdom Panel also tests for 211 different genetic diseases, yet it may hide “at risk” results for some dogs without informing their owners because it considers the findings irrelevant. (And though Wisdom Panel quickly responds to customers, its answers aren’t always consistent.) There’s also a shareable dashboard feature for social-media-obsessed pet owners. In researching this guide, I spoke with Dr. Brenda Bonnett, a veterinarian and the CEO of the International Partnership for Dogs, an organization dedicated to scientific collaboration in the canine research community and the standardization of genetic testing for dogs. I attended a webinar and discussed the validity of genetic testing with Dr. Jessica Hekman, a veterinarian and postdoctoral associate at the Karlsson Lab at the Broad Institute of MIT and Harvard, who specializes in the genomic behavior of dogs. I also consulted experts at two leading dog DNA test companies: Dr. Angela Hughes, a veterinary geneticist at Wisdom Health at the time, and Adam Boyko, PhD, co-founder and chief science officer of Embark Veterinary and an associate professor at Cornell University’s College of Veterinary Medicine, Department of Biomedical Sciences. And I spoke with Leslie A. Lyons, PhD, the head of the Feline Genetics and Comparative Medicine Laboratory at the University of Missouri College of Veterinary Medicine. She’s a leader in feline genetics and often consults on consumer cat genetic test kits. She was also part of the original team at the UC Davis Veterinary Genetics Laboratory that pioneered DNA-based ancestry tests for animals. I also fetched a panel of five dogs (and their owners) to test each DNA kit we evaluated. And I spent two months boning up on canine genetics, speaking with customer service representatives, and consulting my dog’s veterinarian for advice. When I see a dog of an unfamiliar breed, I play a private game of “Guess Who?” and try to match its features to various breed characteristics: That dog’s chest is shaped like a wasp, so maybe it’s part whippet. But it also has a saddle coat and a long muzzle; maybe it has some German shepherd, too. Guessing a dog’s background can be entertaining, but its appearance may be the greatest con in the animal kingdom. “We really like to play the [guessing] game,” said Dr. Jessica Hekman, a veterinarian and dog genomics expert, during a recent lecture. “It’s funny how we interpret how dogs look, and how it doesn’t necessarily have a whole lot to do with what’s in there.” Appearances are so confusing that even dog experts are outwitted. In a 2012 study of 100 shelter dogs that surveyed 5,922 dog professionals, the professionals correctly guessed a dog’s prominent breed just 27% of the time. And a 2015 study across four shelters reported that DNA tests determined one in five dogs were pit bull mixes, while staff had guessed that half the dogs were pit bulls. (Both studies used Wisdom Panel technology.) To determine breed results, a dog DNA testing company collects a sample from a subject and loads the information onto a DNA reader, known as a chip. Then it genotypes the sample along targeted gene points, known as markers. A computer algorithm reads the markers and identifies billions of possible ancestry combinations before interpreting the most accurate solution. Finally, the lab spits out the solution to a mixed-breed dog’s mix. (Pet owners may pay an additional $50 to $100 for inherited-disease detection.) These breed ancestry DNA tests are different from similar tests marketed specifically to breeders. The latter are sometimes more affordable, but they’re too specific and granular for most people. For example, the American Kennel Club offers a $50 DNA test (which doesn’t identify the breed of the dog but rather its exact parentage) as a way of supporting the club’s breeding program and confirming AKC registration. Embark and Wisdom Panel (through Optimal Selection) both offer a variant of their tests for breeders. These also won’t tell you what breed of dog you have; they instead offer genetic health testing relevant to an already-known breed. And they will give you information on a breed’s physical traits, as well as help you avoid inbreeding. The AKC cautions pet owners about using consumer-brand dog genetic tests to make health-related predictions for their dogs, because the results leave substantial room for interpretation. The AKC says the “correlation [to disease] doesn’t mean causation, so a gene that often occurs with a particular disease might not cause it.” The group suggests considering the dog’s lineage, in addition to the test results, to gain a better understanding of potential health risks for your pup. (Wirecutter adds that a responsible breeder should be willing to discuss the results with you prior to your committing to a dog.) Breeder opinion on these consumer-facing products is mixed. In online forums, some say they use Embark for verifying the health status of a dog, while others cite the price and slow processing times as barriers. Some breeders also prefer more traditional, already-established and trusted testing companies, such as the Orthopedic Foundation for Animals and the AKC. If you’re in the process of buying a dog from a breeder (either to get an AKC breed or a mix that’s in high demand), breed ancestry DNA tests can be a useful tool for confirming what the seller is telling you before you spend a large sum on a pup. (Some breeders do test their litters before selling their pups, to identify preferred genetic traits and to limit inbreeding.) If you and the breeder are both prepared to wait the requisite three weeks or so for the results, a test can confirm that your labradoodle is in fact half “labra” and half “doodle” and at limited risk for commonly inherited diseases. But keep in mind that some of the results won’t always be 50/50 for designer dogs (thanks to genetics) or may include results from related dogs in the breed group—the genetic lineage of dogs is long, and the breeding record is less so. If, based on your dog’s looks, you think you have some idea of its breed, understand that the answer may be surprising. And if you’re just plain curious about the breed composition of your mutt, mixed-breed, shelter, or designer dog (not that it will make you love them any more or less, of course), there are solid options that can provide a clearer picture of your pup’s genetic background. In 2019, we assembled a panel of dogs of different ages, sizes, breed appearances, and medical histories: one American Kennel Club Chihuahua and four mixed-breed dogs from across the United States, Puerto Rico, and the US Virgin Islands. Then we assessed how user-friendly each service’s website was, the collection method, the turnaround time, how detailed the results were, how robust the databases were, the number of genetic markers they used, the price, and whether the company invested in further genetic research. Finally, dogs with anomalies in their genetic health reports received follow-up consultations with their veterinarians so we could compare the results. In 2021, we tested the new Wisdom Panel Premium with two of the mixed-breed dogs from our original panel. And we compared the results to those of the company’s now-discontinued Wisdom Panel Health, as well as to those of our main pick, Embark Breed + Health Kit. This is Gus, from the US Virgin Islands. At the time we took this photo, he was 2 years old and weighed 18 pounds. Photo: Amy Roberts This is Sparky, from Puerto Rico. At the time we took this photo, she was 20 years old and weighed 27 pounds. Photo: Rachel Cericola Meet Sutton, born in Oklahoma. When we took this photo, she was 2 years old and weighed 9 pounds. Photo: Kaitlyn Wells Say hello to Swanson, adopted from New Mexico. When we took this photo, he was 5 years old and weighed 65 pounds. Photo: Aviva Johnson Meet Sephora, our control dog and a longhaired Chihuahua. When we took this photo, she was 7 years old. Photo: Dana Wells Dog genetic-testing companies are only as good as the science behind them. None of the companies we spoke with offered specifics into their testing (citing proprietary concerns), and they offered generic overviews instead. Embark and Wisdom Panel both said they use the latest human genetics science to test each dog’s DNA. But, as we found when covering human ancestry tests, big companies rely on algorithms to estimate ancestry percentages—so there’s no way to know their accuracy for sure. Plus, dog breeds are a new-ish invention, and many breeds are closely related (such as the Siberian husky and the Alaskan malamute). You must also consider respective data pool sizes, as well as how many DNA markers (data points) labs use to identify what type of dog you have. Thus, breed reports across labs can get murky really fast. When a pet owner receives the results, a dog’s breed composition is broken into percentages. We compared findings between Embark and Wisdom Panel, and the top breed result matched 80% of the time during our 2019 testing. When the breed breakdowns got into smaller digits, typically less than a quarter of their heritage, results were nebulous. Some Embark breakdowns listed six breeds, and Wisdom Panel listed just three. And when the two agreed on a dog’s overall makeup, they didn’t always align on just how much of each breed was in its genetic code. Hekman, the veterinarian and genomics expert at the Karlsson Lab at the Broad Institute of MIT and Harvard, confirmed that percentage breakdowns are a gray area. “Some of these bits are so small that it’s hard for the computer to make a good guess,” she said. “In my laboratory we definitely don’t trust it below 5%.” She believes companies that use more genetic markers are probably more accurate than labs that use fewer markers. This is why Embark’s results (using 200,000 markers) are usually the most detailed and combine breed results that are less than 5% of a dog’s lineage as “supermutt” listings. Comparatively, Wisdom Panel (using 100,000 markers) will include breeds that are just 1% of your pet’s background; this is more granular, but it doesn’t mean it’s more accurate. We prefer Embark’s approach because our expert said that reporting information down to 1% isn’t any more accurate than 5%, since at those low levels it’s hard to be really sure what breed they come from. Our experts agreed that the accuracy in breed ancestry will improve as technology advances. (For example, one panelist tested their pup with Wisdom Panel three times in five years and received refined yet different results.) To see what the technology reported on our pups at the time of writing, view the breakdowns, below. Both Embark and Wisdom panel updated their testing methods in 2021, here you can see how Swanson’s results changed from 2019 to 2021. Illustration: Dana Davis Both Embark and Wisdom panel updated their testing methods in 2021, here you can see how Sutton’s results changed from 2019 to 2021.

Illustration: Sarah MacReading The results from our control dog in 2019. Illustration: Sarah MacReading Your feline’s genetic code is a mess when it comes to figuring out their family. Cats are far more difficult to identify by breed than dogs, because their DNA is much less diverse.1 And historically, a lot of what we consider to be cat “breeds” have intermixed with random cats frequently and repeatedly, further muddying the genetic waters. Currently, the UC Davis Veterinary Genetics Laboratory, which was among the first to offer genetic testing, can trace cat lineage back to eight geographic regions, rather than to specific breeds. But if there are similarities between your cat and one of the 29 breeds that the laboratory has sequenced within those regions, it will tell you which ones are closely related to your cat. Wirecutter identified nine additional labs that offer cat health screening, ancestry, or kitty paternity tests commonly used by breeders. Basepaws is a newcomer to the market, targeting pet owners of mixed-breed cats. Currently, Basepaws tests for only 21 different breeds, and the company stresses that it’s “NOT a breed verification test, so we do not determine pedigree, and some breeders may mistake our breed test with confirmation of their cat’s pedigree.” Basepaws also doesn’t test for all known cat breeds and admits to needing “many more samples” for its database. We don’t believe the results of either test are accurate enough, so we’ve elected to shelve testing them for now. Embark has a comprehensive breed database, screens for more genetic diseases than its rivals, and has reliable customer service. The Embark Breed + Health Kit leads the pack for both its sizable breed database and the robust list of genetic health conditions it reviews. In addition, the service was founded by faculty of the Cornell University College of Veterinary Medicine and is committed to canine research. Embark also has strong customer support. Embark features a comprehensive dog-breed database including most breeds that are common in the United States. Embark reliably tests for more than 360 different breeds; this includes 90% of the 208 breeds in the American Kennel Club database. It also tests for breeds not accepted by the AKC, such as seven types of street dogs from around the world, the American pit bull terrier, the coyote, the dingo, the gray wolf, the Koolie, and the Volpino Italiano. To confirm the results, Embark’s computers test about 256 quadrillion different genetic ancestry combinations, and its scientists manually cross-check suspicious results. Its proprietary process means the breed results are 95% to 99% accurate, claimed Dr. Adam Boyko, Embark’s co-founder and chief science officer. Breed ancestry isn’t the only driving force for some pet owners. The genetic health results can calm a pet owner’s fears regarding their dog, or it can theoretically help them plan for a future diagnosis or medical expenses, if health results are troubling. (For real peace of mind, pet insurance is a better bet.) Embark screens for over 200 different genetic diseases, but it wouldn’t confirm the exact number. Comparatively, Wisdom Panel tests for 211 diseases, and DNA My Dog’s Nextgen Breed Identification and Genetic Age Test evaluates for more than 100 genetic diseases, although we tested only the breed component for this guide. Boyko said Embark’s inherited-disease screening results are 99.99% accurate. Robust genetic-health testing sounds intriguing, but “please take them with a grain of salt,” cautioned Hekman, the canine genomics expert at the Karlsson Lab at the Broad Institute of MIT and Harvard. “They’re completely unregulated. The link between the test result and the disease is weak.” Currently, the Food and Drug Administration, which oversees animal drugs, food, and medical devices, doesn’t regulate the pet genetic-testing industry. Pet genetics researchers who are critical of the testing industry, including another author from the Karlsson Lab, found no independent studies on how accurate dog DNA tests are. But a Genetics in Medicine report revealed that results from human genetic-testing companies were inaccurate 40% of the time. So I remained skeptical of the health results we received for this guide. Two of the five dogs we tested were reported as being carriers of degenerative myelopathy, a debilitating spinal cord disorder. (Both dog test subjects were desexed, so passing it down wasn’t a concern.) And Embark didn’t corroborate that Sparky, our 20-year-old pup, had kidney disease, an ailment she was diagnosed with four years ago. But Sparky’s vet later confirmed that her disease was age related and not hereditary. I also received an email from an Embark geneticist about my dog Sutton’s results hours before they were officially released. The geneticist said Sutton was at risk for dilated cardiomyopathy (DCM), one of the most common adult-onset heart diseases in dogs. But published research into the DCM gene, known as PDK4, has focused only on 90-pound purebred Doberman pinschers, so my 9-pound dog’s risk of developing DCM was relatively low. Regardless, they offered to chat if I had any questions. (As of writing time, if your dog has genetic markers for a particular disease, Embark will let you know, even if your pet’s breed breakdown means the disease is unlikely to be a problem.) The results were further muddled when Wisdom Panel reported that Sutton was not at risk for the disease. (In light of the discrepancy, Embark’s veterinary geneticist offered a free retest.) Wisdom Panel later confirmed that Sutton did test positive for that specific mutation, but its policy is to hide the findings for any dog that isn’t a Doberman or Doberman mix. “The correlation to actual clinical disease is not supported in the vast majority of these breeds,” said Dr. Angela Hughes, a former veterinary geneticist at Wisdom Health, Wisdom Panel’s parent company. “It’s basically what we consider a false positive,” she said, adding that there are no plans to disclose these results in the future.2 In light of the results, Sutton’s veterinarian recommended an echocardiogram, an ultrasound of the heart. The ultrasound was negative for signs of DCM. Her vet warned that she may develop heart disease as a senior dog, and they suggested tracking Sutton’s health with extra bloodwork during annual wellness exams. But neither Sutton’s veterinarian nor the echo sonographer consulted Embark when giving this advice, which is something our experts encouraged. Whatever the findings, Embark makes it easy to nerd out over your dog’s genetic results by revealing more information—in an easy-to-read format—than any kit we tested. The dog’s breed composition is broken into percentages, and results that are less than 5% of the dog’s genetic code are combined as a “supermutt” listing (unless there’s a closely related breed that’s already present in the results, in which case those small percentages will be added to their near neighbor). There’s also a family tree that goes back three generations, to the “great grandparents.” The genetic health results specify either “at risk,” “carrier,” or “clear” statuses for the more than 200 diseases it reviews. And there’s an inbreeding score, 25 trait markers, predicted adult weight (which was 5 to 10 pounds greater than our panelists’ actual weights in 2019), a “genetic human age,” a “wolfiness” score, and even a list of doggy relatives, just like with human ancestry tests. Embark sponsors the International Partnership for Dogs, a consortium standardizing dog genetic-testing services. Partners of IPFD disclose their accreditation, mishandling protocols, licenses and patents, and their genetic-testing list to increase transparency in an unregulated industry. Embark’s dedication to scientific openness is twofold, since it also partners with researchers to better understand canine genetics. In October 2018, Embark published the culmination of one such study in PLOS Genetics, using 6,000 canine participants, and found a chromosomal link to blue eyes in Siberian huskies. It may seem obvious that there’s a genetic component, but researchers say the proof was abstract at best. They believe large-scale canine genetic testing like this can potentially unlock the genetic basis of aging, behavior, and even cancer. When discussing medical privacy, the Health Insurance Portability and Accountability Act (also known as HIPAA, the piece of legislation that safeguards a person’s medical data) immediately comes to mind. But there’s no equivalent in the pet world. Yet Embark says its privacy policy is modeled after HIPAA and that it doesn’t disclose any information without owner consent. However, dogs are opted in to genetic research (the information is anonymized), and users may opt out by changing their privacy settings. Pet owners can also share results with third parties without granting them account access. They can view a certificate or the full report, email the report to their vet, or download the raw genetic data. Pet owners can also share an interactive dashboard and hide from view any sections, such as the family tree or health results. Geneticists are also available to consult with a pet owner’s veterinarian so they can better understand the results. Embark’s support team was transparent and thorough in its responses. Most emails were answered within one business day, and sometimes sooner. And phone wait times were less than five minutes. We also valued Embark’s proactive approach when a veterinary geneticist emailed us ahead of time to explain that Sutton was “at risk” for a life-threatening disease. Their offer to reconfirm the results, when Wisdom Panel didn’t report the same gene mutation, was also stellar. Comparatively, DNA My Dog and Find My Pet DNA weren’t as forthcoming when we asked representatives about their products (they either couldn’t provide database breed counts or how many genetic markers they use). And at the time of writing, one email from Find My Pet DNA had gone unanswered for more than 30 days. Embark has the largest collection wand of any DNA test we reviewed, and that can likely feel uncomfortable inside a small dog’s mouth. The swab itself looks like a Q-tip and is approximately four times larger than other swabs we used in this guide. Our testers with dogs under 20 pounds said it was difficult to fit the swab between their dogs’ cheeks and gums. The collection instructions were also confusing. Embark has the pet owner swab the inside of the dog’s cheek and under the tongue for 30 to 60 seconds, then enclose the swab in a stabilizing solution tube and mail back the kit using a prepaid box. But Embark offers three versions of printed instructions (the box, a cardboard insert, and a plastic storage bag), and each was slightly different. “I think having a single set of instructions printed on the box would be much clearer and leave less room for confusion,” said Wirecutter's Aviva Johnson and Swanson’s owner. (Since writing time, Embark has updated its packaging, and we’ll review it when we next update this guide.) To see if we could trip up Embark’s breed services, we selected dogs born across the United States, Puerto Rico, and the US Virgin Islands. Embark provided precise predictions of any breed that makes up 5% or more of your dog’s genetic code, which our experts cited as the threshold for dependable home results. Plus, Embark uses twice as many genetic markers as Wisdom Panel, which we think is better for most people since it provides a more accurate identification of your pup’s mix. Wisdom Panel, alternatively, uses fewer genetic markers, so it is probably less accurate, but it’s able to identify rarer dog breeds. If you’re going to spend money on a dog DNA test, it’s best to get one that the genetics experts are more likely to trust. But if you suspect that a dog has a rare breed in its genetic makeup, Hekman recommends Wisdom Panel, which tests for more AKC-recognized breeds than Embark. Embark was also the second-slowest service we tested. The process took two to six weeks, more than any other kit we reviewed. On average, it took Embark 21 days to deliver the results, compared with 18 days for both Find My Pet DNA and Wisdom Panel. Don’t be surprised if you’re drowning in emails after registering the kit online. Embark sent 19 promotional and update emails over three months, more than any service we reviewed. By comparison, Wisdom Panel sent five, DNA My Dog sent four, and Find My Pet DNA sent one email. Finally, Embark is still an investment of $199, at the time of writing. To test an entire dog pack, Embark offers tiered discounts on multiple kits, starting at 10% off—but the information is hidden within its FAQ. We scouted Darwin’s Ark, a crowdsourcing effort that has pet owners submit short behavioral surveys about their dogs—and in return they receive a free DNA test. Collaborating researchers, like Hekman of the Broad Institute of MIT and Harvard, study the research in the hope of understanding what exactly makes dogs, well, dogs. There’s a waiting list for the free DNA tests, and it can take years to receive the results. (I’ve been on the waitlist since 2019.) Anyone can buy a test starting at $249 (reduced to $149 after submission of 10 surveys). Most results for paid tests are available in 90 to 120 days. Darwin’s Ark has 101 breeds in its database and uses 4 million genetic markers. We look forward to reviewing Darwin’s Ark after it receives additional funding and can streamline its testing process for all participants. DNA My Dog NEXTGEN Breed Identification and Genetic Age Test provides breed analysis and a predictive health plan (not a disease screening) with every purchase. Dog owners who use this receive the breed results via email, typically within two weeks. There’s no certificate sent via postal mail, even though it’s marketed as a perk. (We also inconsistently received duplicate certificates from Orivet, which DNA My Dog may outsource tests to, but neither company confirmed this after repeated inquiries.) There’s also no notification when the health plan is ready, so users must stalk their accounts for updates. They must also create a secondary account to access the health plan, which isn’t explained online. And, at the time of writing, we had not received the health plans for three of the five dogs we tested. The company also tests for 96 different dog breeds (a smaller number than with any kit we tested), and it doesn’t disclose how many DNA markers it uses. When we first wrote this guide, in 2019, manufacturer Find My Pet DNA (unavailable as of 2021) featured a website, registration process, customer service emails, and DNA products that nearly mirrored the DNA My Dog experience. All of these factors made this one an easy dismissal. This guide is dedicated in loving memory of Sparky. This article was edited by Catherine Kast, Jennifer Hunter, and Jason Chen. Discerning accuracy among DNA tests isn’t cut-and-dried because the companies are only as reliable as the science behind them. In 2019, Embark said its breed results were 95% to 99% accurate. At the time, Embark analyzed 110 times more genetic markers than Wisdom Panel, so its results were more granular (200,000 versus 1,800, respectively). Since Wisdom Panel used fewer data points, its results weren’t as precise, and it claimed a 93% accuracy rate. (Because DNA companies use proprietary technology, we couldn’t independently verify the accuracy of their breed and health reports.) Wisdom Panel revamped its testing protocol in 2020 and now uses 100,000 genetic markers. The company claims the test’s reports are more precise but has declined to share an accuracy rate for its updated product. Both companies claim to use the latest human genetics science to test each dog’s DNA, but as we discovered while covering human ancestry tests, big companies rely on algorithms, or guesses, to estimate ancestry percentages—so there’s no way to know their accuracy for sure. And a Genetics in Medicine report found that results from human genetic-testing companies were inaccurate 40% of the time. A dog DNA test reveals the likely breed composition of your mutt, with some companies reporting results that go down to 1% of your dog’s genetic code. They can also discern between lineages and provide a DNA tree from both the sire (father) and dame (mother). For an additional fee, you can learn about any hereditary conditions that may be worth bringing up to your vet so you can be better prepared for potential ailments as your pet ages. But don’t rely on these at-home tests to make life-altering decisions for your pet, as they merely provide a potential statistical likelihood—not an actual diagnosis. Discuss any concerns with your veterinarian. All of the dog DNA tests we reviewed needed a sample of a dog’s saliva and cheek cells in order to identify its genetic makeup, which typically required swabbing the dog’s cheek for around 20 seconds. You simply put the swab into the provided container or clean envelope, mail it to the manufacturer, and wait the requisite two to six weeks for your results to arrive in an online dashboard. Dog owners can expect to pay $100 or more for a dog DNA test, and an additional $50 to $100 for inherited-disease detection. For $200 on average, the Embark Breed + Health Kit offers a sizable breed database, wide array of inherited-disease screenings, and reliable customer support. And for about $160, Wisdom Panel Premium offers many of the same features and tests for more dog breeds than Embark—but since it uses fewer DNA markers, its results are less precise.
