I'm not sure how you would go about registering a new breed, but just to get the facts straight...there are NO such things as Labradoodles, Maltipoos, Yorkiepoos(practically anything mixed with a Poodle), Bugs, Pocket Beagles, Teacup breeds, etc. They're all mixed breeds and will never be considered purebred. You can find ANY kind of pet(mixed or purebred) at an animal shelter/rescue near you up for adoption. It's much better to adopt a pet and save it's life, rather than wasting money and supporting backyard breeders and puppymills.
