If you are looking for party or other than the stand Yorkie coloring a dog show will not be of much value for you. The pups you see at the Yorkie shows are there because they have attempted to breed a Yorkie as close to the Yorkshire Terrier Club of America standards. Parti or off color Yorkies will not be seen there. They are primarily pure breed owners. Many breeders now do health DNA testing to perfect their desire to breed healthy pups. You can also the breed identification testing as well.

There are some Biewer owners on this site that will maybe come forth with more info for you.

Good luck in your search!
