The Mysterious Complexity of Dog Breed: How DNA Analysis is Changing our Understanding of Canine Genetics

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

The complexity of breed in dogs 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, accepted breed definitions were established before DNA analysis became widely available. This can sometimes result in genetic testing results contradicting a pet owner’s assumptions about their dog’s breed.

In recent research conducted on 459 shelter dogs in Arizona and California, DNA analysis revealed 125 distinct breeds, with only five percent being purebred. However, the study also showed that mixed-breed dogs were particularly challenging to identify accurately, making up the majority of the dogs in the study. Mixed breeds can be difficult to classify when it comes to DNA testing due to the lack of genetic information available for identifiable breeds.

When considering DNA testing for your dog, it is essential to research different companies thoroughly. The accuracy of test results can vary depending on the diversity of a company’s genetic panel. Even if you receive information about your dog’s breed from DNA testing, it may not have a significant impact on their behavior. 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, highlighting that breed is not a reliable predictor of behavior.
