It would be nice, but don't worry if she doesn't
If it's a big one there may be a lot of entries. If she doesn't win anything it doesn't mean they don't like her, or that you are doing anything wrong as an owner
The shows I went to, I went with no expectations. I didn't expect to win anything, so to get something made me shocked and surprized!
Of course I was happy too, but I wouldn't have been too upset if I hadn't won anything, because I wasn't expecting too. Just remember it's for fun, and there will be other opportunities to enter too
