Sweetlychee, don't feel bad - I didn't realize either that Pembroke's tails were docked!
Now my question is, and at this point it is truly irrelevant: How much 'nub' is supposed to be left after docking for the correct Pembroke appearance? I have seen some Pems with quite a bit of nub left (almost like a stump of a tail, really) and others (like my Chloe) with absolutely NOTHING! Chloe has just a tuft of fur - not even a bit of bone or cartilige (or whatever tails are made of)...
(...wait a minute - how does that nursery rhyme go?... "snips and snails and puppy dog tails..." THAT must be where Corgi tails go
....)
