It is somewhat refreshing to see a breeder come on, to communicate with her puppy buyers, in a direct way that mostly is not too derogatory of her puppy buyers.
Whilst I know that you said you would not post again, and that is fine by me, I do so hope you take the time, to read up on the Yorkie here, and to see "first hand" some of the experiences buyers have had with "breeders" of Yorkies. For a real eye opener go to the Sick and Emergency thread.
Now onto your response to Anastacea: I know it is quite common to ask for a return of the puppy by many by certainly not all breeders; once your puppy owner has bonded with your pup, agrees to provide the health care required and to love this pup; then an alternative to return really does need to be offered. Please consider this.
Consider also that this DNA testing of her dog, did NOT show Yorkie in any major way at all in this dog. That should give you considerable pause. A couple of possible scenarios come to mind, but as the breeder I'm sure you will want to have this breeding pair DNA tested, first to establish if indeed they are the parents of this pup, and secondly to establish what proportion if any of Yorkie is actually in their genes. ONce your have the answers to those questions, then I'm sure you are quite capable of taking this up with the breeder(s) who supplied you with this breeding pair.
In the interim of course this breeding pair should not be bred again, until their provenance is established clearly.
You warranted and sold as purebreed a mixed breed dog, an honest or not error that needs to be rectified, to all the purchasers of this particular litter, not just this one poster.
In respect to Joanna; she expected to purchase a Yorkshire Terrier that has been bred to standard. This standard is set by the YTCA and approved by the AKC. The standard sets the weight out at maximum of 7 lbs. A 20 pound dog is significantly over this standard. A $300 dog if that is the price you sell your purebreds at, as a purebred should be a good healthy representation of the breed. That includes size, color, coat and temperament. The buyer should ask for and expect as a good breeder, that you health check - prescreening breeding tests, special tests for the Yorkie breed, and that both sire and dam have passed these tests. If you are unfamiliar with the range of what needs to be done, there are threads on here that delineate that: also you can go to
www.chic.org, and look up the very basic requirements there for this breed.
And for your information a show "quality" dog is ususally never purchased prior to 6 months old; maybe show promise not quality. LP is usually evident in pups as young as 8-10 wks old, and as a breeder of YT's you should already know how to check for this. All I can say about this breeder "doingnothing" for a crippled dog, is you "buy" your breeder first and then your puppy; that is a caveat for the pet owner, it is triply so for breeding/show quality dogs.
