COI 27.... You can't be serious...

Well it's true.... I checked it three times off the KC Breed records Supplement AQ2 April to Jun 2013. The KC have therefore accepted that which they say they don't!!!! A mother/son A Daughter/father or a brother /sister mating gives a score of 25 according to the Kennel club and is no longer acceptable..... So how on earth does somebody manage to generate a score of 27 and still register their pups with the Kennel club?
