If you are planning to sell the pups you probably should get the parents tested. DNA tests generally cost between $60 and $110 dollars but may be well worth the cost.

Pet DNA can be done at many places; Veterinarian, some Petsmarts, and sites on line under Pet DNA testing has many places where you get a kit and send it off. Even the dog whisperer has a web site for testing.
