from the neighbor down the street.
Have to disagree with you. Just because someone breeds out of their house or might be your neighbor does not make them irresponsible. You should research ALL breeders AND shelters before purchasing as shelters have been know to lie just to place a dog. Even the most conscientious of breeders can err. Should any prospective breeder do their research and educate themselves accordingly? Absolutely, but just like in humans it's not a perfect process and to expect as such is unreasonable.
