Some companies use two independent methods to test each mutation for the most accurate results. When looking for genetic diseases, the method used to analyze the genes is also important. The top tests match your dog DNA with more than 200,000 genetic markers, whereas inexpensive tests are likely to have far fewer markers in their databases. However, accuracy can also be determined by how many genetic markers the test analyzes. As we touched on before, the greater the number of dog breeds in a company’s database, the more likely you are to get an accurate picture of your dog’s genetic background.
AccuracyĪ range of factors influences the accuracy of the results. Ultimately, unless you have a legitimate reason you need the test back sooner, consider the overall quality of the test before worrying about the turnaround time. Some companies aim to give you your test results within two weeks of receiving your dog's samples, whereas others take as long as six to eight weeks. If you want your dog's DNA test results in a hurry, pay close attention to the turnaround time. You’ll also find tests that offer a rudimentary overview of your dog’s general health – by analyzing hormones, vitamin levels, and other vitals – as well as those that can tell you if your dog has any food or environmental allergies or sensitivities. Some more basic tests only screen for one or two conditions, such as the multi-drug resistance-1 (MDR-1) genetic marker, which identifies dogs who will suffer severe reactions to a number of common medications. The most comprehensive dog DNA tests screen for over 150 different health conditions, genetic abnormalities, and more. This lets you monitor your dog, with the assistance of a veterinarian, and may end up giving you some precious extra years together. These tests don’t necessarily tell you that your dog has a health condition but that they're predisposed toward a certain condition. Some dog DNA tests provide a range of health screenings in addition to the breed information. Some manufacturers of cheaper tests have databases of fewer than 100 breeds, so it’s more of a gamble as to whether your pup’s ancestors will be represented. The companies with the largest databases can identify your canine companion from over 350 breeds, including more than 99% of breeds recognized by the American Kennel Club, so you have virtually all your bases covered. The larger the database, the more likely you’ll get accurate results, especially if you have a suspicion that your four-legged friend has some rare breeds in the mix.
Key considerations Number of breeds detectedĪll companies that offer dog DNA tests have their own databases featuring the genetic markers for certain dog breeds.
