If indeed you have a silky, then all pups she carries will be silky mixes. There's just no way around genetics.

Which registry are her papers through? If it's AKC, you should have a pretty good lineage on her (assuming it wasn't falsified). With CKC, it's a crap shoot IMO, since they have very loose standards on what it takes to prove you have a "purebred" anything.

As Chachi said, it's possible that you have a full bred yorkie, but one who just wasn't bred properly to breed standard. If you are really concerned, ask your vet about DNA testing, but don't buy the ones from online or Petsmart. If you are to have any standing in a court case, you will need an official one done.

Then comes the next matter. If she is a silky or a mix, then you would have to prove the breeder KNOWINGLY deceived you. That's pretty hard to do. Then you have to look at whether or not you would even be eligible under the laws of your state to sue. In the end, suing may end up costing you a whole lot more money than you could possibly be eligible to recover.

But because you have questions about her lineage, it's now imcumbent on you to not try and pass the puppies off to new buyers as full yorkies. Otherwise, you could very well find your self on the other side of the courtroom aisle in a couple of years.
