You'd be surprised - that's one of our major things we investigate are puppy mills. This sounds like more of a case of someone who just keeps breeding their dogs and then sells them. There are a lot of responsible breeders out there and there are a lot that aren't. Many of them just want the quick buck for people who are stupid enough (yes I went there) to pay $500 or more dollars for a puppy. The sad thing in this case is if they are actively breeding, then obviously there should be veterinary care involved. They obviously don't care about selling off their dogs before they are properly weened. The OP doesn't really seem to be helping the situation any. The other real problem is that really isn't a whole lot that anyone can do about it. There are very few laws out there that govern this type of activity - most states don't have any. Here in Texas, as long as you are providing your non livestock animals with food, water, and shelter - there isn't anything that can be done.
This is why there is pet over population and various groups and state/local governments spend millions of dollars every year on various campaigns to stop breeding, spay/neuter programs, "no more homeless pets", etc. These are the people who are contributing to the problem instead of trying to be part of the solution. It's always the same - "Oh, we don't have any money to take care of them". Then don't buy or adopt pets, it's that freaking simple. Just like with kids - you don't have the money and/or are not going to provide them with basic health care, you probably shouldn't have any.
