OP, that "cheap" puppy just may end up costing you BIG TIME. Please reconsider. There are reputable breeders where you can get a nice healthy pup for not too much more cash. And please don't forget that the initial cost of the puppy is PEANUTS compared to the expenses of caring for a pup. Vet care, premium food, flea/tick preventative, grooming and grooming supplies, not to mention all the little extras that most of us like to have for our dogs such as clothing, strollers, pretty leashes, etc....
I hate to think of you getting this obviously poorly bred pup and being slammed with high vet bills. From the looks of that site, this is a broker. They will know nothing of the parents of these puppies, and probably don't even know who the sire is
They just breed these poor dogs to death and they get no vet care, no love, live in filth, and have litter after litter, only to be disposed of when they can no longer produce pups. Please don't support this type of breeding. Keep saving your money and use that time to find a great breeder. Everyone here will help you find one in your area.
I hope that you'll stay and learn about the breed, and share stories and pictures of your new pup.
