thank you for the reply.
while i in general agree with the idea of general regulation (just breed enough dogs that the shelters stay empty and not more than x litters per bitch), i think operators of unethical puppy mills should be hanged and i wouldn't be opposed to banning certain breeds (like the ones that were bred to the point where they can't breath and we call that cute), banning the sell for money seems strange - and not only because it would be quite easy to circumvent.
