Sorry you had a bad experience.
There are all kinds of people that show: the good, the bad and the ugley!!LOL Dont let one bad person keep you down!! I suggest that you go to shows and meet the exhibitors, not before the show, but after they are done. They will have more time to talk to you then. There will always be that exhibitor that will not give you the time of day, but you will also meet some very fine people. Most will be stand-off-ish at first. They probably have seen it all when it comes to people that want to start showing and breeding. Most of these people find it way to time consuming and expensive or get a bad taste in their mouths when their dog doesnt win and quit. Also, most exhibitors are very protective about their lines and dont want to make them available. You will have to win their trust first. Best of luck!!
