Guest, perhaps you should have thought about this before either choosing to breed this cross or allowing the accidental mating to continue. Now the puppies are a reality you will just have to be very conciencous about vetting your buyers, certainly visiting them in their own homes and maybe asking for references from vets etc. until you are perfectly satisfied that they are not the sort of person who would abuse this tempting cross. Any doubts at all I would turn them down and err on the side of caution.
