Now for this breed, you want to go to a reputable Breeder here, and not from some guy named Luigi on the street corner. Many Cotsi are in shelters because the person did not do any research on what to expect with this dog. THey are not for everyone. You could have 140 pounds of Liability, agression or Illness. But the breeder first, and research. The breed club is the best bet to go to for info, not the Classifieds.
