Border Collie working cow dog puppies with ABCA registration. The puppies are five months old and ready to go. They've been wormed and vaccinated. These puppies are descended from excellent working bloodlines. Tony from Steve Sturtz in San Angelo, TX is on both father and mother's papers. Both have a strong instinct for herding. Father is a large dog weighing 60 pounds, and his sire is Chris Knight of Kentucky. Mother is a smaller dog, weighing close to 40 pounds and bred by the legendary Willie. Both the mother and father are fantastic with children. All pups have been handled by children over the last two weeks and are doing well. This is a tried-and-true cross that has produced excellent results in previous litters.
