I am sure there are others that I am missing. Sorry!!
To answer your question about costs. People can only charge what people are willing to pay. Sad to say, but if someone wants to pay a high price for an unregistered Yorkiepoo there will be someone out there willing to sell it to them.
In MY OPINION, the Biewers are a bit different because we can trace them all back to the original yorkie parents. There is a standard that we should be following if we are going to show and/or breed them. Of course there are people out there that do not want to show to validate the correctness of their Biewers, but insist on selling all of their puppies as show/breeders for high prices. Most responsible Biewer breeders register their litters in Germany, microchip their puppies, have shown their adults, DNA parents and puppies, do health screenings. I am sure you recognize this list as what the responsible yorkie breeders do also. Can the breeders of the unshowable partis and the chocolates say the same thing (Again, I know not all Biewer breeders can say this either, so don't hate me for saying what I FEEL should be done.)
