Ah you mean the crooked tails.. yes, they are visible now when the tails aren't docked.
But they do not need to be so because of an injury, it might be hereditary state. Earlier the tails were docked and the "problem" was gone. But as the tail is a part of the spine... if there is a problem in the tail, there might be a problem in the spine, too... earlier you just didn't notice it because the tail wasn't there.
Now a crook in the tail is considered a feature that needs to be taken into consideration in breeding.
We had a docked yorkie before. Of course the undocked tail seemed off and odd before I got used to it. Now I like it a lot as long as it is beautifully carried
