LOL. Our dog was exactly like yours. There was this, don't really know how to describe it, well a "wall" made of thick bushes (it was about 2 meter high) and it really was thick so u could not walk through it or anything. Our dog always found a hole where he could escape from. The rest of the area was normally fenced so the dog couldn't escape but we felt no need to put fence to where the "bush wall" was. So one sunny day me and me grandfather set up this electring wire there, used to keep animalls such as cows from breaking throught their fences. Well then the dog tried once, touched the wire with it's nose and ZAP! The dog didn't go near to that wire for something like 6 months.
