The last straw came the day a passerby allowed his pooch to leave `` a golden blessing'' on the floor-length window of McCann's office. From the window's vantage of Veterans Park, McCann often sees dog owners `` using our park as an open-air toilet for their dogs.'' For complete story, see today's Sun Chronicle.
