KC do not tell you how and what to breed ..You breed whatever you want..As stated earlier only difference between a good type of russell and a parson is a bit of paper ..I dont register all my pups sometimes Ill register one out a litter so what are its litter siblings Russells or parsons ???It was a long time joke with me registering did it for fun ..Most of them come from the same stock anyway...Some people just cannot grasp the true facts just like the borders if its registered it cant work, if it hasnt been registered it will if bred right ..A bit of paper is just that a bit of pape
