I looked at their site and they have a lot of dog breeds for sale. This looks more like a puppymill operation to me. I would contact my local animal control and file a report. One of my girlfriends work for the Sheriffs dept here and they do alot of investigating animal abuse cases...sick people out there ...I made her promise to quit telling me those stories.
Call your vets office and ask them who you can file a report with. There is a lemon law in most states that breeders have to pay vet bills for a sick puppy.
You took your puppy the next day to your vets and have documented proof you bought a sick puppy.
Good Luck..it is a lot of work to get to the right person...I would start asking around...I am sure there are others with sick puppies from this breeder.
