I actually think this is a very good question. When Winston and I go for a walk, he is told to sit and wait at each and every corner, car or no car, when I say OK and start walking across the street, he follows. I would never intentionally allow Winston to run free without a leash, but you never know, maybe a door or gate was left open accidentally...he has to know to sit and wait for me to get him and not run into the street...no chasing allowed with me, the more you chase them, the more they run.
Any other useful suggestions?
