Our dog Kaz is confined to our house garden when we leave the property. The perimeter fences have an electric wire running along the top of them and she very soon learned she couldn't jump over the fences. But the garden gate doesn't have an electric wire for obvious reasons and she equally soon learnt that she could jump over the gate and we would find her at the top of the drive to greet us when we returned. We bought a new, higher gate, which stopped her escape for all of a week. We screwed a tall board to the new gate - still she learnt to jump the ever higher and higher gates! So we have tried another cure - we took off all the unsightly additions and set beads, bobbins and bells on rigid wires across the top of the gate. They would roll under her paws, we thought, if she tried to jump the gate. But in the last three weeks since we put them up there have been no signs that she has even attempted it - so far!! By the way, the lovely wrought iron brackets were made a few years ago by my brother, Mark Schofield, during his blacksmithing days.
