File it under Things It Never Occurred to You to Worry About if you like. But in 2003 New York magazine article about misbehaving dog walkers, a stockbroker named Joanne told how, made suspicious by her cocker spaniel’s desperate need for relief when Joanne arrived home from work, she draped the dog’s leash just so on the banister before leaving for work to see if it got moved.
