Rearing is a natural reaction to an action that has been part of the horses make up since time began.
This behaviour is a tool that wild stallions will use when they fight each other for breeding rights.
They usually combine the rear with striking out of a front leg (fore leg).
Colts will often exhibit the same behaviour, but in a playful manner whilst around other colts or fillies.
This is a natural herd behaviour, whether in the wild or in a domestic setting and an important part of growing up.
Rearing with a rider is often a form of napping to avoid what is being asked of him, but you need to rule out all the possibilities that could attribute to the rear.
Saddle
· Is the saddle fitting correctly?
Bit
A bit that is too small for the horse will pinch or cut into the mouth.
· Is the bit suitable for the horse?
The bit could be too severe, causing pain.
Teeth
· Has the horse been seen by a dentist lately?
Does he have sharp teeth or sore gums?
If the rider is heavy handed the horse could rear through pain.
