Fun Fact, 67 Foot Radius places the fence boundary in other Peoples yards and the street(if centered on house), if it was centered at back of their house the fence would have shocked the dog before it got halfway to the road not to mention its radius would encroach even more in peoples yard.  Both agreed dog was half on road and half on yard, placing it 30 feet PAST the edge of the fence...it only got there if the fence was defective, the dog didn't care, or was charging full speed when got shot and momentum carried it to the street.  Still think the dog owner has no fault in this???
