When Jake was younger and more energetic, we tried one of those underground fences. He learned that if he ran through it really fast it wasn't too bad. Then he wouldn't come back through. I remember one time he wasn't anywhere near the fence and he started getting zapped by that collar. I had to run inside and switch it off. He was throwing up from it.

I know Max would do the same thing. A real electric fence might be a better idea - and you gave me an idea. I wouldn't have to worry about him digging under if I built a kennel (would have to be like 9 feet high!) and put the electric wire around the bottom of it.

With electric fences near the ground, what happens when it rains? Do you get zapped just standing on the wet ground?
