This is the definition of my horse when Ridden, if I am on the ground and someone else is riding he is okay until I leave/get on another horse/get on him myself.
When that happens he starts pulling the bit, really mouthing it and chomping, he wont stand still then he yanks the bit HARD. When asked to walk on from a halt he'll leap into it or jump into it, he also feels very tense! When aksed to move up in speed he'll bolt.
Could this because by a ridden who was very rough and was always kicking and yanking?
He is EXTREMELY sensitive, and pain has been rulled out.
What can I do to calm him down?
