Do you mean that the vet's paperwork identified her as a Yorkie mix or that the papers you received from the breeder said she was a mix?

If it was on your vet's paperwork, I would just ignore it. Someone, maybe the vet tech or someone at the front desk that enters all that kind of info into your pup's records probably saw the floppy ears and assumed that because the ears weren't standing that she was mixed with something. They assumed something that wasn't correct.

I have two Yorkies that don't have standing ears. One has ears that are completely flopped and the other has ears that stand halfway with the tips flopped.

Your girl looks all Yorkie to me, welcome to Yorkie Talk. BTW, when your new expect it to take a while for your posts to show up. They have to be approved by a mod before they show up. This is done to weed out spammers. After you have made several posts, they will no longer have to be approved and they will show up instantly.
