Don't do what a lot of people do......drag their dogs around for HOURS before they go in the ring. By the time they get into the ring they have no dog left!
When you first get to the show, leave your dog in the car and bring your crate and chair in. You need the crate so you have some place to leave your dog during the walk-thru! Bring a water dish, a favorite toy, and whatever is part of your normal training day. Find a space and set up, then take a walk around to get the lay of the land. Find your ring, and if they're giving out numbers pick yours up.
Get your dog out of the car, give her a pee break, and take her into the show and take a nice walk around. Not serious training, just a nice walk. Maybe do a couple of puppy pushups. Give her a nice rub down. Come up with some kind of game that you can play with her that doesn't disrupt the other dogs. Put her in her crate and let her chill for a while. If she's not used to being crated at class, sit in your chair for a while so she doesn't worry that you're leaving her. But DO walk away after a while, briefly at first, to give her a chance to get used to that.
Depending on how long it is until you show, take her out again and have her do a few quick puppy push-ups, a little bit of heeling, a quick game, then back into her crate. You can probably do this sequence a couple of times....use your judgement. You want your dog enthusiastic but not over the top! But you also don't want to leave your best performance outside the ring. Since you have one of Christine's dogs I don't think you have to worry about not having enough dog <G>
Good luck, have fun! Go show off your dog!
