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

DNA analysis has revolutionized the way we understand the concept of breed in dogs. Halie Rando, an assistant professor of computer science at Smith College, who led a recent study on the subject, believes that while a dog’s genetics may align with a specific breed, widely accepted breed definitions were established before the advent of DNA analysis. This means that genetic testing results can sometimes contradict pet owners’ assumptions about their dog’s breed.

In her study, Rando analyzed DNA samples from 459 shelter dogs in Arizona and California and discovered 125 distinct breeds, with only five percent being purebred. The majority of the dogs in the study were mixed-breeds, which can be challenging to identify through DNA testing. While genetic testing can provide valuable information about a dog’s ancestry, it is essential to note that it does not always accurately reflect their behavior or temperament.

Rando recommends that consumers research DNA testing companies thoroughly before submitting a sample. The accuracy of results can vary depending on the diversity of the company’s genetic panel. Even if you do receive information about your dog’s breed, it may not have a significant impact on their behavior or temperament. A genetic analysis conducted on over 2,000 purebred and mixed-breed dogs found that behavior is more closely linked to individual dogs than to their breed. In conclusion, while DNA testing can provide valuable information about your dog’s ancestry, it is crucial to approach it with an open mind and keep in mind that behavior is ultimately determined by the individual animal rather than its breed.
