Well, it's her dog, and so she has the right to decide what to do with her. She is also right about there being too many dogs already. Perhaps she just decided she didn't want to show her. As far as tricking the show judges, well obviously that's just stupid and wrong and you know it. Nobody is going to help you know how to do that. I'm sorry you are so angry, but she wasn't your dog in the first place, and breeding her wouldn't have given you the puppies, they would have belonged to her actual owner, so I don't really see why you are so angry. If someone had spayed your dog, okay I could see it, but she wasn't your dog. And putting work into it and getting her ready to show, still taught you plenty about how to go about it, so you didn't come away with nothing, unless you choose to see it that way.
