Very true Lee - electronic fences  do not contain determined dogs - the muni needs to rewrite that regulation.  We have a  nice neighbor dog that used to run thru its electronic fence just to go on walks with us and our dog. We never enticed it or encouraged it. We'd head out of our yard and a few minutes later hear yelping and see the neighbor dog running shaking its head to join us. He'd keep going like that  until he was out of range of the fence.  On return he was reluctant to re-enter his own yard.
