Woman Outraged After DNA Test Reveals $1,750 Dog Isn't the Breed She Wanted

It has become a popular trend using DNA to find out your family tree. There is even a hit TV show called Who Do You Think You Are, which helps people learn about their roots. But did you know you can also use DNA to learn about your family pooch? Les Trent reports. This is me. My DNA. It helps make me who I am. You've seen the commercials. Family tree DNA will help you discover it. Learning all about yourself through DNA. Actress Lisa Kudrow even has a TV show, Who Do You Think You Are, dedicated to revealing your roots. That sort of changes everything. Using the same techniques, you can test your dog's DNA. But you might not like the answers. Go get the squirrel. New Yorker Phyllis Vonsaspie wanted to know if her $1,700 designer dog Emma really is a shorty, a mix of Shih Tzu and Yorkie. Come on, go get the bones. And Cliff Mintz of New Jersey was eager to know if his dog Moose is a purebred Havanese, which is what he paid for. And what about this little doggie in the window, which we found at the Chelsea Kennel Club in Manhattan? We went shopping for a new pooch with Kathleen Summers of the Humane Society of the United States. Don't be scared. We were told by the store's manager three different times that the dog was a purebred Catan de Tullier. He's a purebred. Catan de Tullier. Purebred Catans are known for their cotton white coats, like these Catans shown at this year's Westminster Kennel Club dog show. So we bought Jack for $950. Yep. Let's go, bud. Then we took the little guy straight to the vet where we had his cheek swabbed for DNA, just like they do with humans. In a few weeks, we're gonna find out what breed you are. What did Jack's DNA reveal? He's not just like my dog at home. Adam Boyko is the chief science officer and co-founder of Embark, a company that specializes in analyzing dog DNA. He says Jack is not a purebred at all. He's a combination of Maltese and Havanese. Same deal with Emma. According to the DNA tests, the Shorkie, who was purchased from a breeder in Washington State, is not a Shorkie at all. She's a mutt, part Shih Tzu and Pomeranian. I felt deceived. And Moose, he's no purebred Havanese. This little guy who was purchased from a New Jersey breeder is a plain old mutt, part Shih Tzu and part Havanese. I think it happens a lot more than people know. As for that dog we bought at the pet shop, the manager of that pet store in Manhattan insists Jack is a fullbred Catan, even when we presented our DNA tests. It's basically a mutt. We have documentations and registry papers that say that it's a Catan from the breeder itself. Jack now lives with a loving family in Baltimore, and they couldn't care less whether he's a mutt or not. We don't care if he's a Catan or a Maltese. We fell in love with him as soon as we met him. The pet store sent us this registration document signed by the breeder, which lists Jack and his parents as Catans. They say this document, not DNA, is the industry standard for determining whether a dog is a purebred.
