Our backyard is now Stalag 13. We finished putting and electric fence around it so Daisy will stop escaping. Though, I can't see what the big deal is with the fence. Even at the strongest it doesn't zap, is just tingles and feels really weird.Like a 9 volt on you tongue, but feeling that in your hand and up your arm. But it seems to be working so far. Still, the electric fence makes me feeling I I should be doing Sgt. Shultz impersonations... "I know nuthink!"
