I have to admit that I moved off of the farm about 50 years ago, but
it seems to me that we did not electrify the top wire of the fence.
The electric fence was lower than the top of the fence and located to
the inside of the posts. The height of the wire depended on if we had
cattle, hogs or sheep in that pasture. This type of fence would
reduce the chance of contact as would stringing a grounded wire or
non-conducting strand above the electric wire in the problem areas.

Experience is the thing you have left when everything else is gone.
