I'm not sure why I need a PM AND a reply here. But now that I've seen you've replied here, I'll answer you here as well.
When you are referring to taking a zebra to a "zebra show" then people are going to infer that you are talking about an actual competitive event. Your friend is not competing in zebra shows, because as far as we can all tell there aren't any. He is doing exhibitions with his animal at fairs and such.
Being clear in what you are trying to relay through the written word is important if you want people to have an idea of what you are talking about.
