If you're puzzled about the breed of your dog, you aren't alone. There are a number of dog DNA companies to help owners uncover the mysteries of their mutts.
But a Marketplace test found dog DNA tests geared toward consumers won't necessarily give owners the answers they're looking for.
Marketplace recruited two mixed-breed dogs, one purebred dog and one human (Marketplace's very own Travis Dhanraj) to test the accuracy of consumer dog DNA tests. Their DNA was sent to four companies that claim to specialize in dog genetic testing: Wisdom Panel, Embark, Accu-metrics and DNA My Dog.
Elinor Karlsson, the director of the Vertebrate Genomics Group at the Broad Institute of MIT and Harvard, says when a dog appears to be a mix of many breeds, you shouldn't rely on conventional traits — like looks or behaviour — to determine the breed.
"People tend to hone in on particular characteristics that they associate with breeds," said Karlsson, "but once you mix many different breeds together, the traits start interacting with each other."
