For easy leading and control of your horse, bits and headstalls will provide the results you need.
Things to Consider:
Collars -- As an easy alternative, collars can make leading an easier job, particularly for beginners, and require less lead line, preventing possible tangles.
Colors and reflectors -- For night riders or hunters, collars are available in orange for hunting safety and reflection.
Bit guards -- To prevent your horse from being pinched by their bit, guards can easily be added.
