Stop moving and stand stock still. Only move again when the pup is calm. A little quiet praise when she stops also, depends on just how excited she is.
Try to keep the led arm still when walking with the lead not trailing in her sight, same with your clothes wear ones that don't flap.
Practice the 'Leave' command in other situations and use it for this too.
If she starts close to home march straight back and give her a time out.
This is high spirits and excitment, you want to manage it not squash it completely.
