Last year we rescued an abused pony. He is about 10 years old and you could not get near him. He had to be tricked to be caught.
Today he is a pain. He wraps his body around anyone entering the field looking for a treat and he was taught to give his body to me while still afraid of all humans.
He now knows the technic to beg for treats and has no problem with wrapping his body around any potential doner.
