In some ways people are all the same, regardless of economic status. A certain luxury high-rise residence decided it was necessary to put this notice at the entrance.
Pet debris? Old dog collars? Ragged chew toys? No, I think the message is, “Don’t bring your dog’s shit inside.”
Our home is on a corner lot which seems to attract a lot of dogs who wish to leave their gifts at a crossroads. Most owners bag and remove but there are the sneaky ones who walk their fecal machines in the dark so they don’t get seen and then there are the “polite” ones who bag the slag and then leave it rather than do the heavy lifting and carry it home to do their own disposal. On the plus side there’s a lot less cat poop in the garden with a resident coyote in the area.
