Not exactly Yorkie related but with our first litter of Australian Shepherds, two of them were going to Germany. She requested early on that they not be docked because of the European rules. I had no problem with that since I was sure of her intentions to purchase. Only thing though, you don't always know who is going to buy which pup (especially in the case of Yorkies that all kinda look the same when born - unlike Aussies of different colors) so you would have to have a very solid agreement and deposit on a specific one to not dock the tail. I would hate to not dock it and then the person back out and you not have any other interested buyers who want a full tail.
All that said, I personally like the docked tail the best. I understand people's concerns about it but having been standing with the vet when he did the two litters of Aussies we've had (minus the Germany ones), I didn't think that there was much pain involved. Kinda like a baby boy's circumcision... really glad though I had girls and didn't have to make that choice.
