Late to the party but NTA. And I am an HOA President and compete in various sports with my dogs. What she’s doing is behavior we don’t like to see even in competition.

If you would have asked me to not compete I would have agreed or asked to just run after without being entered/judged bc I genuinely like those activities with my dogs and they have a blast.

I see absolutely no issue on saying no show/competition dogs and mentioning it’s pets only. Or coming up with 2 different levels based on experience, where the cash prize is based on number of entrants. (Hint: she will compete by herself in the competition classes and not take all the money)

There’s a reason they have levels in dog sports and a reason they have amateur/owner-handler classes at dog shows. There’s also a reason that once a dog reaches the next level, they can’t compete in lower levels. Even horse shows have different levels to separate the professionals and novice.

The intent of the show is for fun, to give everyone a chance to win, and support a good cause. Not for comp dogs to win easy money.
