pitc9 I feel your pain. Recently I posted about the neighbors grandson on one side of us giving us problems. A few years ago(when we first put up the fence) our neighbor has this vicious beast that came after my dogs! I hauled dirt and filled in under the fence and had bricks lining it! Her dog would come 8 feet on my property to go around the wooden back fence to get to the chain link side! The dog now has a bad heart and has to keep from running around so she now keeps it away from the fence!
Right now both of my dog's are leashed, Mandy for her heart and Lacey for her leg so we aren't having any problems walking the two of them in the fence But I sure never dreamed when we spent $2,000. on a fence to keep our dogs safe and able to run loose that everything OUTSIDE of the fence would be our greatest problem! I wish you luck in finding a solution.
