The Double Doodle, also called the North American Retriever, is not a purebred dog. It is a cross
between the Goldendoodle and the Labradoodle. The Goldendoodle is a Golden Retriever crossed with
a Poodle and the Labradoodle is a cross between the Labrador Retriever and the Poodle. Therefore
the lines of a Double Doodle are Golden Retriever, Labrador Retriever and the Poodle.
