I saw this on News Channel 8 in Connecticut. It's an interesting discussion (and a sad story) based on the "Pet shop lemon law." Basically, you can only get your money back within 15 days of purchase. And most stores will only give you money back if give them the dog. And of course, we can guess what will happen to that poor puppy in most cases.
For those interested, check out the text of the stories:
My thoughts on this are wide ranging, as I can understand both sides of the arguement. I'm very familiar with this particular store, and their dogs are very well-treated, clean, and come with their first vaccines. However, the store doesn't make a point to x-ray each dog to search for all the minute problems. I don't think we could really expect any store, or even every shelter, to go that far.
Hopefully the community can come together to help the people and dogs who are mentioned in this story.
