On a list I am on a very good breeder mentioned that she had one puppy left in her litter and that it might be hard to sell, even though it is one of her favorites, because people take the attitude that there is something wrong with the last puppy. The truth is that a good breeder matches the pups and their new homes. The last puppy left doesn't have anything wrong with it -it just hasn't found the right match yet.  Don't fear the last puppy of a good litter from a good breeder-it may be the perfect puppy that has been waiting just for you!
