Bull puts his head through a fence

Recently I saw Fritz the bull push his head through a fence by the water trough while a cow was drinking.  Fritz wanted to check the cow out to see if she needed some of his loving.  This fence has wire attached to it to stop the cattle from putting their head through the fence.  Fritz pushed the wire back.  I was concerned since the wire has pointed ends and I didn't want the wire ends to poke Fritz's head.  The wire didn't when Fritz withdrew his head.  To fix this problem I added some more wire to this wire and wrapped it around a pole to hold the wire in place.  So far this is working.   We are only days away from me letting Fritz join the ladies.
