Are you willing to travel some? If so consider looking at the classified section of YT, there breeders and rescuers list pups.
I agree with Nancy. Look at the ASPCA's website on puppymillers. I seen a video on one of the news channels before (can't recall which one), they showed very impressive webpages for puppies for sale, but when they went to the house to pick up the puppy it was horrific to say the least. Over and over again it happens, people are getting scammed out of money. Please, reconsider doing on line as I'd hate to hear that someone stole your puppy money or your puppy arrived in ill shape. Best to see for yourself.
