Its not confusing at all, it was meant literally "Curb your dog". A person was required by law to walk their dog in the curb (where street meets sidewalk edge). You were not supposed to walk your dog on the sidewalk. That doesn't bother me as much as pet pet owners that assume you don't mind if they walk their pets on your lawn instead of the grassy area by the curb (sidewalk edge). I don't pay a mortgage to have my property used as a toilet for their pets. "Its not ok to walk your pet on my property" You can't pick up urine which kills my grass and you certainly can't pick up soft stool which inbeds itself into the soil and of course the sidewalk; it just smears.
