Horses can be difficult to lead if they are excited, nervous or just feeling good!
There are techniques that can be used to help you control a boisterous horse. When you are leading a horse you need to be aware of what is happening around you so that you can avoid trouble and so that you don't run into someone else.
In the birdcage there are often pedestrians as well as horses. Your job is to keep control of your horse and prevent injuries to people and horses.
Generally it is better to keep your horse moving as space is often limited. Keep checking behind you and beside you as well as in front of you.
