Direct-to-Canine Genomics

Dan Collison and Elizabeth Meister at NPR share their dog's genetic testing results from MMI Genomics. Collison and Meister, who bought Dovekie in January, were told that the puppy was "a Golden Retriever chocolate Lab mix." However, as the dog grew older, "it was clear this dog was anything but this mix." So they opted to purchase the "Canine Heritage" swab testing service from MMI, who determined that Dovekie was a mix of four breeds, and not what they had expected. As it turns out, Dovekie is a mix of golden retriever, wirehaired pointing griffon, bearded collie and miniature schnauzer. "This means that Dovekie's mom, Charlie, whom we met and felt confident was a purebred golden retriever, was anything but. It also meant that Romeo was no chocolate Lab."

Looks like Romeo's got some explaining to do.
