Is this also the same pony whose face is swollen and folks have said it wasn't the electric fence and perhaps a vet should be called?
Is the swelling still there? Was a vet called out?
If this pony is on your parents farm, who in your family or family friends has a lot of horse experience to help you.
It is sounding more and more that you do need hands-on guidance that you cannot get from a forum before you get hurt and the pony ends up hurt and/or with some very manners
