good luck to you. i have to disagree with one statement that was being said here. this is "jmo" if you don't see champions all over the pedigree, that does not mean it is a poor quality yorkshire terrier. you can still get a great standard of the breed with out this. having champion in the pedigree for "some" (not all) is just a selling point to increase the value of the dog.
i have seen champions throw out some not so great quality of the standard yorkies but this doesn't mean it isn't a wonderful loving pet.
a breeder sees faults in their sires and dams and tries to improve these faults to keep the integrity of the yorkshire terrier breed.

i was having a hard time trying to put my thoughts down so i hope i did not offend anyone.

yes, champion in the pedigree is wonderful but if it is a good reputable breeder who strives to improve the breed and its health, you should not say "no" to the breeder just because their is no champions in the pedigree.
