I wouldn't say it's normal but I see it from time to time. There is an old guy a few houses down that lets his go wild on a open piece of land near by and they will often venture well beyond that to my house and a little way down the street. Sometimes I hear him calling them but often he'll be ignored for a while, while they do their thing. With the mystery dog that has disappeared again, he just showed up. Sometimes I am driving and I see dogs walking leisurely down the street. Still it is not the norm but you see it from time to time. Trellum, would Reba be called semi stray in your country since she stays outside most of the time? I know she frightens quite a few walkers.
