All God's creatures are beautiful. But IMO as a die hard pure Yorkie lover. Adding Poodle to a Yorkie takes away some of the excentric Yorkie traits...Yorkies do best in multiple dog households. Why not get a Poodle and a Yorkie to have as pals in stead of mixing the 2?
Besides, mixing 2 breeds you are not going to always end up with the exact same blend of personality or traits of the 2 breeds.
