arabian show

So I have arabs and they are registered if I am showing them at the Arabian society next year how do I get them ready where do I clip and what should they look like :))

It depends on what classes you plan to show in.

Go to some Arab shows and watch. Walk through the barns and get a good look at how the horses are groomed. If you are going to jump into this you need to be informed and aware of the rules. I haven't shown in Arabian shows for years and would need to re-educate myself as things change.
Go plant your buns in a chair on the rail and get your eyeballs on the real deal.
Have fun...and it will be a lot more fun if your prepared!

Yep, go to a show to just watch first. You'll be a lot better off for your first time showing, then.
