Not actually true, Anwen - in some cases, the KC will accept a name change if the breeder agrees to it, although not entirely sure if that's the only criterion. I know someone who's done this, as they didn't like the name the breeder had chosen (and in that case, don't even think they had approval from the breeder, but that's a whole different story ..... I'd be livid if that happened on a pup I'd bred).
In the case I know of, the pup was registered as "Affix Name" and was then changed to "Affix Othername of Owner's Affix" if that makes sense LOL.
