*Equine Behaviourists?*
A friend is having trouble with her horse and isn't sure how to deal with him. He has began to rear at the smallest sign of having his bridle taken off, clinging onto his bit in his teeth and squashing my friend. The vet has been out and thinks it's behavioural and give him clean bill of health.
Is there anyone in this area who deals with things like this and would be able to help?
