Red Barn Kennel Positively is a Puppy Mill Chariton, Iowa

In December 2005 we bought our female boxer from Fred and Sharon Loney.  I have to say that while these rip off reports are alarming, we've never had a single problem with our little girl.  She was healthy the day we picked her up (my husband met her with our pup at the airport on his way to vacation), and she's been healthy so far.  She's six years old now and just as happy and energetic as she was when she was little.  However, for our second dog we bought another boxer, but from a different breeder.  Not because of anything we had against Red Barn Kennel, but just to have a different bloodline.  He came from a breeder that showed their dogs, and his parents were AKC pointed, and his grandparents and such were Champions.  Both his parents were large, beautiful dogs, and the breeder was an AKC registered breeder.  He is the one who has all the health problems.  Not that they are bad problems, he just has skin allergies that range in symptoms from general itchiness to complete loss of hair on the sides of his body.  And I question his intelligence at times, too.  He's also very lazy, which is completely uncharacteristic of a boxer.  But I most certainly do not blame his breeder for his problems.  This is what you're risking when you buy a purebred dog.  Purebreds by their very nature have more health issues than pound puppies and dogs.  THEY ARE INBRED TO CARRY ON SPECIFIC GENETIC TRAITS!!!  That may be a reason why you've had such bad experiences with your pets.  I'm not saying that for sure, but you have to look at it as a possibility. 
I will say one thing I noticed about the quality of the service we got from each breeder.  Our male's breeder called and emailed frequently when he was young just to check up on him.  She would always ask for pictures of him and ask how he was doing with his training, i.e. housebreaking and good manners in general.  Practically as soon as he was born she began teaching him and his littermates good behavior.  She even went so far as to refer to him as our baby.  Once we got Pepper from Sharon Loney, we never heard another word from her.  While we were buying her, she was very polite, and accommodating to our needs.  She drove hours to the airport to meet my husband and hand over our puppy.  But once the transaction was done, that was the end of it.  I've even sent her pictures and a handwritten letter of our dog just to tell her how wonderful she is, how smart, sweet, and sensitive, but I never heard anything back. 
Without seeing firsthand the conditions the dogs were living in, I can't and I won't say for sure whether Fred and Sharon Loney are running a puppy mill.  I have owned a dog that did come from one, and I will tell you the differences between him and Pepper is vast.  He was sickly all the time and looked less and less like a boxer as he grew up.  As far as picking up a puppy from the airport that was sick, you are required by the airline to obtain a health certificate on that animal if it is going to fly.  A vet has to have given your pup a clean bill of health when he examined her, so she could have contracted something while in flight.  It's not the same temperature at 35,000 feet as it is here on the ground.  It's very cold in the cargo hold where they keep the animals. 
In closing, I would just like to point out that just because you buy a purebred dog from a breeder, and that pup is AKC registered, it does not mean that you will receive a perfect animal.  You are still getting a living, breathing thing, and it can get sick and it will someday die.  Just because an animal is AKC registered, does not mean that it is superior to any other animal you could have gotten.  It only means that you are getting an animal that conforms to the AKC breed standard (and that both the parents were AKC registered).  I'm not defending anyone here.  I'm only telling my experience with this particular breeder and stating some facts that maybe you haven't thought about. 
As for our Red Barn pup, we couldn't imagine our life without her.  Nor would we want to.  There's nothing like coming home to her bright eyes and wiggly butt.  She's like our vary own ray of sunshine, she completely lights up our life.  She cute as heck, smart as a whip and completely in tune with our emotions. When we fight, it visibly takes a toll on her.  When we're happy, she's twice as happy.  Even when we have family and friends stay with us for a few days she accepts them into our household with that same wiggly butt and even gets emotional and depressed when they leave.  But of course she gets lots of love from us in the meantime!  Even if her breeder was questionable, we wouldn't trade her for the world, and we wouldn't go back on our decision to get her.  She has completed our life in a way that simply no other dog we've had has been able to.  Simply put, she's perfect.
