Your yorkie’s appearance has nothing to do with the competition, but he must be purebred if competing at an AKC-sanctioned show. However, if you have a mixed breed, the United Kennel Club allows you to compete at trials.
Competitors can also be neutered or spayed. In fact, a neutered dog tends to give a better performance because there are fewer odiferous distractions.
As in conformation classes, your yorkie must be at least six months old. You will find that most of the dogs in this competition are up to a year and a half, for it normally takes at least that long for their dogs to outgrow their puppy pranks.
You begin at the novice level. The title is called Companion Dog, or CD. In this class, your yorkie must be able to heel both on and off leash, walk round two people in a figure eight pattern, stand and stay, come off-lead, finish (go around you and place himself into heel position on one command).
He should remain in a one-minute sit-stay and three-minute down-stay with dogs on either side of him while you remain 30 feet away.
The next level is open, the Companion Dog Excellent title, or CDX. In this level, everything is done off leash. The judge runs you through a heeling pattern that includes at least two stops, right and left turns, and several about turns.
Then you must perform an off-lead figure eight around two people, a drop-on-recall, in which you call your yorkie from 30 feet away. Make him lie down when the judge signals you to do so, and then finish the recall with your dog coming to sit it front of you.
There are two retrieving exercises in the open class. One plain retrieve, where you tell your yorkie to stay, throw a dumbbell, send your dog to retrieve it, and have him return to a sit in front of you.
This is also done with your yorkie going over a jump both on the way to retrieve the dumbbell and on the way back to you.
Each exercise is topped off with finish. Next exercise is for your yorkie to jump over a broad jump without touching it. The jump consists of boards lying only a few inches from the ground.
The final exercises are for your yorkie to remain in a sit-stay for three minutes and a down-stay for five minutes – lined up with other dogs and you out of sight.
