I spotted these signs with Max the Airedale Terrier at a newly installed dog park in the ravine near Casa Loma. The city has installed similar signs at most of the dog parks and I have seen large posters on bus shelters too as an attempt is made to get people to stoop & scoop and to keep their dogs on a leash unless they are in an off leash area. I'm not sure how successful they will be.
