I always walk her with a leash even when we go out back. My yard is not fenced in and I live in a wooded area with all kinds of critters like fox, deer and whatever else is back there in the woods. I never let her go off leash. She is just to darn picky. She won't go even if the grass is to high, she will go on the sidewalk. The grass has to be the perfect height

.
I don't blame her, the grass can sometimes get taller then her and she probably likes to see what's going around her when she doing number 2.
