Well no matter how much we go on and on about accidental litters, health testing, cross breeding etc, etc I think we all know that there are some that do not want to be educated and no matter what is said they will continue to do their own thing and as long as people continue to buy pups from them they will continue to breed. More and more buyers are starting to get the message now and asking questions and seeking reputable breeders of their chosen breed. It would also be a good thing if all the internet sites that carry puppy adds were to list the hereditary defects and illnesses of each breed with the warning that buying a pup from non-health tested parents could cost them more than the original price they pay for a pup! This should be the first thing they see when they click on their chosen breed.
Educating buyers will go a long way to ensuring that these people do not continue to line their pockets at the expence of the welfare of their dogs and the puppies they produce. If they cannot sell them they will not breed them!
