Great responses everyone... I couldn't agree more. I really think it's best to keep the thoughts flowing to also remind others the essence of breeding and to also make people become aware if the breeder they get their puppy from really breeds to improve.
I've read most articles about responsible breeding which talks about the future of the puppies brought into this world. I agree with yorkiekist that another responsibility to be noted is to be able to evaluate the bitch and the breeder who owns the bitch who needs the stud service...making sure the line to improvement won't be cut short by falling into the wrong hands.
