You and I still have a different interpretation of pedigree lol. My dogs are pedigreed dogs - working pedigrees! They are the back bone of good lines of working dogs over generations of breeding and carry information on the working traits etc.
Not sure why you are so defensive, plenty of working breeders mix and match to get lines of dogs suited to certain environments, it is nothing new really. The odd splash of kelpies, huntaways cattle dogs find their way into lines of collies and visa versa depending on what is required. They can be documented in their working pedigrees on working registers. There are plenty of kelpie collie crosses etc with papers that have been purpose bred. If you were to continue your line of dogs then you would create your own pedigree, I know people in the working world who have created their own lines.
