The Kennel Club Computer holds records of pedigrees for all dogs registered with them. Therefore when a breeder applies to register a litter the Dog & Bitches registered names and KC reg. numbers are given on the application form, this means that if the breeder or a puppy buyer applies for a KC printed pedigree once the pups are registered then the pedigree is simply printed off the computer - the database being update by this new generation. However, there is currently absolutely noi guarantee that the pedigree is a true and accurate repesentation of the pups ancestry, as all these details are dependant on details given by the breeder in the first place. Of course, the vast majority of breeders are honest and reliable, and are keen to ensure the integrity of the breed records, but the system is open to abuse by the "fringe" element. either deliberatly falsifying records or being unsure of the parentage (eg 2 different males may possibly have mated a bitch).
All KC registration documents include the wording that accuracy cannot be guaranteed. A longstanding and ongoing discussion is taking palce about DNA testing/positive identification (microchip or tattoo) to ensure that pups are actually the issue of their registered parents.
Of course, as the other respondents have stated, you can also buy blank forms to fill in your own pedigrees or do them on your computer. Hope this makes it all a bit more clear, even if it cant reassure you about the absolute veracity of pedigrees.
