As was already said, let the breeder guide you.
Before you go, make a list of traits you want in your dog; really think about this and don't just say 'friendly'. Think about what you want to do with your dog and base your traits around that. For example, if you just want a pet that will lay around the house and take the occasional walk, you'll want a dog that's more laid back, not high energy, still willing to work (since you'll want good leash manners), and sociable. If you are interested in performance sports (rally, obedience, agility, etc.) your list of traits changes slightly and might include higher energy level, willingness to play/tug/fetch, solid work ethic and desire to learn, structurally sound, etc.
Share this information with the breeder and let them help guide you to the right do to fit your life. If there isn't a dog that's a good fit, no matter how cute they are, be willing to continue to wait for the right dog. You won't be disappointed.
