Start by going to ring craft classes. You have a breed where there is a lot of competition so when you have some training enter her into a few open shows and see how you do. First you and the dog must enjoy showing, you must have an interest in the breed over and above winning an award card.
Most people start showing with the family pet, they learn the ropes and how to assess a dog so they get to know the good from the very nice. Once they have the experience they usually buy in a puppy with a view to showing and continue to get advice from the breeder. At this stage you are hooked and will either go from strength to strength or find that you loose interest and retire.
If showing is for you it is good fun, you make lots of friends and learn loads and loads about dogs and people in general and your own breed in particular.
