Alot of people have this picture of a puppy mill that they get from the animal sites..sickly pups, horrid conditions, half starved dogs in cages with dead pups. Those are the extreme cases that get busted. There are mills operating at minimum level as far as health wise, feeding and vetting. While most of their "stock" have never seen the light of day, they are fed and vetted. These are the ones the law can't touch because they are doing everything just above board. I don't believe in breeding your pet quality dog with the neighbors for that one litter of cute pups..akc or not, it's no better then a mill pumping out less then quality animals.
I believe a reputable breeder is one who has researched the breed, knows the history and possible genetic issues that come with it and are willing to give up there whole breeding program if they find their lines less then desirable for the breed. These people do it because they love it, and want to perserve a great breed to be admired and enjoyed for generations to come. They don't believe in mixing their beloved breed with another to meet the demand for a new fad puppy, they had solid ethics, and would do everything it takes to keep their lines pure and clean. JMHO
