By showmanship do you mean for her looks? If so this is called conformation. There is a lot to learn about grooming for this aspect and even to know if your dog is breed standard enough to even enter a ring. It is very political and opinionated.

My best suggestion would be to find a Dog Club around that does Conformation and begin going to practices. You need to know how to have the dog move correctly, running and walking and how to show the dogs strong features off. This is what most clubs will teach you.

I am planning on showing my male in conformation. I have been active in showing in obedience and field for a long time. We also have done some agility showing.
