Hmmm. I think it depends where you live or the town ordinance. Before I got our fence and I was able to walk Logan, of course she did her business whereever. I can't time it or stop her in mid session. The entire area where I live has huge front yards (and backs) plus grass between the curbs and sidewalks. Logan peed by a telephone poll one night just as the owner pulled up. She ranted and raved forever how she pays blah blah amount every week to keep her lawn clean. I happen to know she has an uncontrollable, vicious little dog (it bit 2 neighbors and attached other dogs) and I've seen her kid walk the dog at the school yard across from her. I've never seen this kid pick up her dog's poop, but that's OK. . I told her 1) she pays way too much to her gardner 2)about her kid 3) I can't stop a dog from peeing. I just walked away. I always carry poop bags in my hand, Can't do a thing about pee. Regardless of it being a public place, we are responsible for our properties, even the sidewalks, ie: if they're cracked or dangerous. I can't even count the dogs that pee and poop on our property, but everyone picks it up. One time a lady was surprised her dog pooped, having just did it, and saw me, apologized, almost cried. No big deal. I have her a poop bag. No big deal. If I had to, I would have gotten it. There must be a poem "Ode to the Doglover" somewhere.
