How to make my dog excited for an agility show?

Well, this is my third year showing my Cocker Spaniel, Daisy. She is turning 6 this month but sometimes she acts like she's 10 years old. .__. Sometimes it really just depends on her. Anywho, I have a 4-H Dog show today and it's for Agility. She's not the fastest runner but I know she can do better than she has been for a couple weeks. http://www.youtube.com/watch?v=T9jcTfhxW9c That's my dog and I and I was really amazed about how she could go that fast...Well, to the point. Is there any way I can possibly make my dog happy or excited before going in the ring? Just the other day at our last 4-H session, she ran faster than ME. (Oh, and don't say treats please, I can't use them in the ring. I plan to use them before and after she competes)
