Call your local kennel club and find a conformation training class. AKC.org has a list of member clubs and there should be one near you. These are the people that show their dogs. Get involved there, they can help you.
You can enter her in a show once she is 6 months old. She will need to know how to gait (walk on a lead down and back) without jumping around, and at the appropriate speed, and she will need to be able to be examined on the table where the judge will look at her structure, teeth, body condition, etc. She will have to stand still and allow herself to be examined. A free stack, on the floor, is desirable.
Is she a long coat or a short coat? If a long, she will need to be groomed appropriately.
Like I said, you need some mentors to help you and you will find them in your local all breed kennel club.
