AVOID THE words that label tiny pups- teapot, micros, mini- those words. Those breeders are breeding for the wrong reasons usually. Ask about the parents/ grandparents- health as far back as they (the breeder) can go. Ask about previous litters, how those puppies are doing. Health guarantee, find out what the breeder will do if your puppy becomes sick. That's a few that I can think of. I know there will be more. I don't know about shipping puppies. I- myself- don't like the thought of them being shipped. Have fun looking! Keep asking us stuff when you need to.
