I don't believe anyone, who truly loves animals, would buy knowingly from someone who treats animals with no respect at all.
Oh, they do
Some people justify their decision by reasoning that they are "rescuing" the puppy, even though they are actually just lining the pockets of the breeder which encourages them to do it again
But even more just buy "on a whim" - there are regular protests outside the stores that specialise in selling puppies, and the protesters say that so many people who go into the shop are saddened and shocked by what the protesters tell them (and even sign the petition), but come out of the shop with a puppy anyway
So how do we go about changing things? I would be the first to fight for such changes. No way should dogs live miserable existences like this.....
But, when you go to choose a puppy from a Kennel Club Recommended breeder, you feel that you have chosen someone who is regarded as professional. Or at least I did. Are these people actually visited before they become registered? It is ok to have had all the eye and other health tests, but is the environment examined? I don't know.
One of the best ways of changing things is through education - if you find out as much as you can, and pass it on to as many people as you can, then hopefully, slowly, things will change. If you don't know what KC Registration means in terms of guarantee and quality for instance, or how an accredited breeder is different from a regular KC registered breeder, then a lot of that information is on the KC website
Other things that make a difference is becoming familiar with the breeders in your area, their affixes and more importantly, their ethics - if the same telephone number is included in adverts for a range of different breeds of puppy in your local paper for instance, then the chances are they are (at best) a commercial breeder - you can often find out (through the internet) where the kennels are, too
Get to know your local dog wardens, chat in pet shops and vets surgeries - become an active member of the dog loving community in your area and you will soon begin to learn which breeders are respected and which are to be avoided. Then you can spread the word and hopefully, fewer people will buy from the "bad" breeders through ignorance
