The popularity of Dog DNA tests is increasing, but can they be trusted?

The complexity of dog breeding is often overlooked by many people, according to Halie Rando, an assistant professor of computer science at Smith College. While a dog’s genetics may align with a specific breed, widely accepted breed definitions were established before the advent of DNA analysis. This can sometimes lead genetic testing results to contradict a pet owner’s assumptions about their dog’s breed.

In recent research, scientists analyzed DNA samples from 459 shelter dogs in Arizona and California and discovered 125 distinct breeds. However, surprisingly, both the scientists and experienced shelter workers were unable to accurately identify mixed-breed dogs, which made up the majority of the dogs in the study. Mixed breeds can be particularly challenging when it comes to DNA testing as the accuracy of test results relies on the genetic information available for identifiable breeds.

Consumers should conduct thorough research on DNA testing companies before submitting a sample for testing. Even if you do receive information about your dog’s breed, it may not have a significant impact on their behavior as a genetic analysis conducted on over 2,000 purebred and mixed-breed dogs found that behavior is more closely linked to individual dogs rather than their breed.
