April, have you trained with this obedience club in the past? And is the class you are interested in an intermediate good manners obedience class or an intermediate competition obedience class. Knowing basic good manners commands would mean that Dora is ready to progress to an intermediate good manners class but may not mean that she is ready for an intermediate competition obedience class. Having trained in competition obedience, if I went to a new training facility and the trainer wanted to evaluate my handling skills before allowing me to join the intermediate class I would know that what she's saying to me is that she wants to evaluate my relationship with my dog, my knowledge of the exercises that will be covered, and my skill at giving the commands for those exercises. An example would be the "sit" command. Telling a dog to sit in a good manners class is just that ... you say "sit" and your dog sits. Giving a "sit" command in an obedience class would be either saying "sit" or using the hand signal for "sit" which would be looking at your dog, not using your voice but instead raising your left hand, palm upturned, with your elbow bent at a 90-degre angle. Using either method of command, your dog is expected to sit on your left side within a couple of inches of your leg, its shoulder lined up with your leg, facing straight ahead and either looking straight ahead or up at you. Other commands that your dog should know for an intermediate obedience class are "heel", "down", "front", "finish", "over", etc.
All this should have been explained to you in a kind and informative way because that's how as novices we learn and that's how good teachers teach. I hope that this was just a miscommunication on the part of someone who assumed that you would have already known this ... an assumption she should not have made. If you are thinking you would like to take some competition obedience classes with Dora let us know. There are a number of SM members who do train and show in obedience and some great books out there to help you learn what it's all about.
