First of all, your training class should know of (may even run themselves) ringcraft classes. Whether or not you decide to show her, the training is never wasted! They will know of local Open Shows (the best way to start) or you can get one of the weekly dog papers, either Dog World or Our Dogs. They list all upcoming shows. Go along to one or two (without your dog) and see how it's run....look at the other dogs of your breed and compare them to yours, and how yours compares to the breed standard (open mind needed here!)
Then have a go! Good luck!
