For a mating to take place between a Rottweiler and a Miniature Pinscher would be extremely difficult without human assistance. The size difference would mean that it is unlikely that intercourse would occur naturally without one of the Dog's getting hurt. For this mating to take place artificial insemination may be needed. Remember that crossbred puppies are worth considerably less than pedigrees so it may be worth mating two Rottweilers or two Miniature Pinschers.
