I am pretty sure the info will be in your contract.
From my experience, usually, people who get pet puppies that turn out show worthy, you can work with the breeder if you want to change from a neuter/pet contract to a show one. They generally will demand health clearances and a title before you could breed the dog. As your dog gets older, around 6 mos, if you are sure you are interested, the breeder can help you find people he trusts to evaluate your pup and tell you if your puppy has potential. That said, it is a very expensive hobby. There are so many other venues you can do.. agility, lure coursing, obedience <cough>, etc. I recommend you attend some shows... maybe ask a breeder if you can go with them, help with their dogs in return for asking them lots of questions and getting some experience at show.
