hi Janet,
the first question I have is do you have 3-rail pipe fencing? If you
do, the only way to stop it, is to put wire fencing over the pipe.
Trust me, we have fought this for ages!
They rub out their manes from shoving their heads through the pipe.
If they are just really rubbing, I'd definitely give it a shot, it's
worked great for us.
