While I am sure the pup was adorable, as all pups are, but enriching the people who abuse animals as puppy mills do is not something I would want to be a part of. The parents of that poor pup remain locked in filthy, tiny cages having no interaction with people except a dish slipped in a slot once a day.
You can get a nice pup from a reputable breeder for about $1200.00. Contact your local AKC sanctioned dog conformation club:
American Kennel Club - Club Search and Directory
They have breeder referral people who will give you names of reputable breeders in your region.
