I just recently got a German Short Haired pup. The backyard is almost completely fenced except for about 20 feet that is between our detached garage and house. I need to put up some sort of fence to keep the dog in. I would just use chain link, but the area where the fence needs to go in covered with concrete. I don't want to spend a boat load of money on this fence, and I don't think the landlord would like me busting holes in the concrete to set posts. Any ideas?
