Two days? He knows sit? Then stop, stop training altogether. Oh, its two weeks. Ok, that gives you a little time. If he is ready for competition in two weeks, he should be beyond treats. But that is just me. You cannot wave a strip of bacon in front of him in the ring.
Rally is fun, and you can repeat commands, and move your hands and such. I think this causes people problems. There is nothing more annoying than some old lady with a pitch in her voice telling her little monster dog to sit seventeen times. For one thing, the dog tones you out. So if you are repeating commands at all, stop. If you halt and tell the dog to sit, and he does not, help him, run your hand down the back and a little pressure to the waist or tuck under. Do not allow him EVER to hear a sit command and not end up in the SIT position.
At the same time, you do not want to go over board, cramming for this test in two weeks. Several times a day, in your drive way or on your daily walk, just do some four sign routines. (Signs in your head): Halt sit, walk forward four steps, Halt Sit Down Walk around, walk forward six steps, 1 step 2 step 3 step halt, walk forward, 360 degrees left. This is about 1 minute or less of training.
Mix it up, come fronts, finish left halt, finish right forward. Do these little four sign routines three or four times in a walk, or a couple of times a day, but do not do much the day before.
Get to the show early, check out the map, figure out where any issues might be, and do a four sign routine with one or two of those in them, maybe do another four sign routine and then stop, relax with your dog. Do the walk through a couple of times, and Good luck.
