Dressage is about showing the judge that you can get your pony to do what you want him to do, when you want him to do it!
You and your pony have to follow a set of instructions laid out in the dressage test.
A judge marks the test. They give you a mark out of ten for how well you carry out each instruction. At the end of the test the marks are added up and the winner is the horse and rider with the highest score.
The good news is that you have probably already started doing some Dressage!
When you are riding at home and getting the pony to do the things that you want him to do you are already practising the basics of dressage.
All of ours rallies start with a dressage based warm up, to help improve the partnership between pony and child.
