Mine has a cropped tail, but I think it is inhumane to do it. I asked the breeder not to, but he did anyway. I was more than a bit angry
My next yorkie, I will refuse to buy with a docked tail. I think they are pretty with tails (although, I do have to admit it is stinkin adorable when Paddington wags his little nub)
Someone on here told me once that the tails break easily, and that is why they get docked sometimes.
