How do you change your horse on my club?

I'm sorry, but I need more context to understand your request. Please tell me:

* What club are you referring to? Is it a real-life horse riding club, a virtual game, or something else?

* What do you mean by "change your horse"? Are you talking about swapping horses, switching equipment, or something else entirely?

Once I have more information, I can better understand your question and give you a helpful answer.
