Never did I say that your dog has to PLACE OR has to WIN it's class. Simply show it. At a show you will meet people that are willing to mentor you and help you out. Maybe even give you a discount on a puppy or two to encourage you in the right direction w/ your breeding line. If you have the cajones to just get out there a handful of times, even if you know you don't have top dog, that speaks volumes of your dedication to not only your dog and your goals, but the breed as a whole and wanting to be a part of it's future to conform to standard and creat a well bred, purebred Yorkie.
You said it yourself: "Getting a dog that will win in the ring is something you stive for...your ultimate goal." And that's exactly what I said. You just have to show. Not necc. do well. Showing teaches you and helps one grow within the breed. Its one of the best places to start to become an ethical breeder!
I hope you didn't get the Diet Pepsi in the keyboard!
