If you want to show I would go along and watch many people are friendly
If your breeder shows they will be able to give you a good idea. There are lots of "levels" of showing and most people start with a dog they have bought before they thought about showing, there is a fair bit to learn for you and the dog.
Even getting 5/5 I was pleased with the card and we learnt a lot sometime we didn't come last, I was very pleased with that and eventually we got a Best of Breed or two
The following dog we bought can from a breeder who showed and we had more success even getting a CC despite been a newcomer.
My dogs are entire for various reasons including showing but also because my older boy was a little shy and castration would have made him less confident.
Give the showing a go it's good fun
