* Arrive at the ring late, although this does happen, you dont wana run in that ring bad impression
*Do not forget your bait, squeker, or whatever gets your dog more focused, and keeps his/her attention on you.
* DO NOT wear no hoochie mama clothes girls defiently a bad impression, no short skirts that baerly cover the goods, no low bearing shirts, no spike heels at a dog show, god forbid you step on a dogs paw, or break a heel. No jeans, this is a very dignified sport which wants to produce dignified handlers.
* Do not abuse your dog, thats just wrong, always work with your dog, and keep the best attitude you could possibly achieve
*Arrive early at shows, I would say depending on the breed and your grooming procedure, a good hour before ring time should suit you
*Keep your dog in good physical condition even if he/she is just a juniors dog, the appearance of your dog shows your comminment to its health, this goes with coat condition as well
*Dress to Impress, For young ladies this means appropiate length skirts or pant suits, something that will not block your dog, for instance when showing a small breed do not wear a long skirt, this will only flap in your dogs face when it moves. For guys a nice shirt, dress pants, and jacket, will do good. Remeber to keep in mind the weather.
* In the ring keep a happy attitude! Not only will you feel more comfortable but your dog will be more comfortable, remeber tension will run down that lead.
