"rare colours "

what is it with multitude of people breeding and advertising disqualified coloured frenchies and charging up to £4,200 each and why is the kc still accepting registrations for these dogs .
its one thing to be a genetic carrier of an undesirable trait be it health or cosmetic but to deliberately breed these faults and then sting unsuspecting people for extortionate amounts seems almost criminal , i cant see the justification if the breed standard does not accept them breeders should not deliberately produce them, occasionally things pop up its the nature of recessive inheritance but if your breeding pedigree dogs stick to the STANDARD.
