No pictures were posted. On your papers does it say yorkie or silky? I’m sorry you had to learn about breeding one of the hard ways but both parents need to be fixed. When breeding we should only breed to better the breed and in order to get lines worth doing that it takes a lot of time with a reputable breeder. If a breeder just lets you buy dogs with out a spay or neuter contract then those are not great lines that need to be continued. Just being AKC and healthy doesn’t mean a dog should be bred. It should be a perfect example of the breed and you should know everything you can about their lines. It’s tough and very expensive to be a reputable breeder. If you have any questions do ask them.

Papers say Yorkshire terrier. Vet called them silky ask difference he said due to the long flowing silky hair.

Well that't not true. A silky is actually a different breed one similar to the yorkie but not a yorkie and its not based on hair. A yorkie is just a yorkie whether they have soft silky hair or wire hair.

I don't want to sound harsh, I'm just concerned about puppies and now a mating pair that carry the Blue gene. Even tho your vet gave your dogs exam head to tail, and did blood work, look what you got out of this litter, a Blue born from "healthy dogs ok'd to breed" per your vet. Examining a dog does not ensure it is bad genetic free, the only way to do that is researching the mating pairs parents, grandparents, great grandparents, plus several generations back, what you're looking for are genetic flaws that can be passed down from generation to generation. If you spent "many hours of reading" about breeding these little silkies, Yorkires do you even know what breeds you have? You should have read it is necessary to research for genetic disease that will be passed down to future generations. Or did you just read about birthing, whelping, when do you know when the momma is ready to deliver. There is more to know about breeding then whelping. And this vet you have, to tell you the only difference between a silkie and a yorkie is long flowing silky hair, I would be looking for another vet. There is a similarity of color, size and temperament between Silkie and yorkie because the Silkie originated from the Yorkshire terrier years back, but, the Silkie terrier is it's own breed and recognized by the AKC and there are differences between the two. So because your vet said your girls are Silkies because they have flowing silkie hair is the reason you're saying your females are Silkies and disregarding your AKC papers read Yorkshire Terrier? Your Blue born, did you take this puppy to your vet to show him / her what your "healthy" mating pair produced? I cringe to even think what your vet would say about a Blue born since this vet does not know the difference between a Silkie and a yorkie. I have already stated this in my other post, but I'll repeat it again, this puppy should not be sold, it is not ethical to sell this puppy that could become very sick, possibly die in a few years. If you have any love at all for the yorkie breed, please have the mating pair spayed and neutered, please do not chance another Blue being born. And PLEASE get a vet that knows about yorkies.

Did you do any DNA tests on the breeding pair?

Would DNA show any genetic issues?

I have a couple of empty memory cells that need to be filled lol

Don't answer that I just googled and yes, DNA will show some genetic disease, fantastic for breeders, cuts out time and money researching, fast and easy.

A helpful post by pstinard in 2013 suggests there is a genetic test that can determine "which dogs are carriers of the 'd' (recessive Blue Born) allele."

See https://www.yorkietalk.com/forums/4251692-post8.html

The post makes further reference to and quotes from a 2007 paper.

Yes there are several series of tests, but probably after the fact know, it would be good to know what it shows. Most breeders do the tests on their breeding pairs prior to breeding, clearly there is some mutation(s) present.

YTCA has DNA test recommendations that are availablle and recommended.

I was just filling those empty memory cells, absolutely fantastic what a simple DNA can tell you.

I’m not sure I would blame the vet 100% on not knowing the differences. Silky’s are not that well known and no matter how good the vet they can’t know every single breed because there are so many.

As I understand the full comments by Tx-Debb, the vet's intention was to use the "silky" as a description to contrast the difference between the hair of the dogs (as opposed to "Silky," as a breed identifier).

Believe my earlier post exacerbated the "silky" vs "Silky" confusion when I referred to my neighbor's oh-so-sweet Silky-Yorkie mix.

I'm sure sorry for my part ...

here are pics of my Yorkies.

Updated pics of little guy as of today.

He's a cutie! There is a simple DNA test to determine whether or not a dog is blue born. The technical name for blue born is "color dilution alopecia," and the DNA test is called a "D locus test." If you get that test done, you will know for sure. Here is a link to some companies that perform that DNA test:

D-Locus (Dilute Coat Color)

The health problems others have described in this thread usually start around the time of transition from puppyhood to adulthood. I would definitely recommend that you have your blue puppy tested, and if his results come back as d d (homozygous dilute), you should definitely stop breeding his parents and not breed his siblings either, since they could be carriers.
