Bottom line, nothing these hard hearted mean spirited people said about your Fancy is going to change her. Showing is just that -- it is showing the world what you have to offer -- and then having one or two trained individuals compare all the dogs in the class to the standard and selecting the dogs that most closely match the Club Standard.
Keep your chin up, be proud of your little Fancy and have fun. If it is in your heart to show her, then go for it and don't let hateful bitter people interfere with your fun.
sending hugs to you and Fancy
