So many people are against cross breeding, I have tried and tried to figure out why but it just does not make sense. If you can guarantee that both the mother and father are checked out and are healthy and have no genetic faults or diseases that can be passed on they why not?? You want the pups to be of very best quality which is why you would have to have a good standard of the yorkie as well as the poodle. The two breeds once mixed together make an excellent combination and offer many benifts. Such as hypoallergenic factor that yorkie poos are great for people who suffer from allergies. And no one can tell me that that is not true because I do suffer from allergies and I have personally experienced that I am not allergic to yorkiepoos as I am with most breeds. If you are striving for the best than why not?? I know plenty of people who would rather have a yorkiepoo then a yorkie. But everyone has their opinions and just as many will disagree as many that will agree.
As far as the size and weight goes I am in complete agreement with yorkiek9trainer.
