It is up to you whether or not you want to purchase a puppy without meeting the breeder. Some breeders are willing to do phone interviews and e-mails and that is sufficient and they will ship the puppy. Be careful though. If people are selling exclusively over the internet, then their operation is not open to the scrutiny of customers. It is easy to make a website look like all is wonderful in the world.
I personally won't sell dogs to people I have not met and won't ship puppies, but then I sell the show line pups that you want to stay away from for some reason. That's fine. Other breeders show line and working line ship regularly. That is up to the breeder.
Maybe if you post your general location and the distance you would be willing to travel, people can hook you up with working line breeders that you might be able to visit.
