>Really? I’ve never seen a dog that would walk on that kind of grate. My dogs avoid them like they’re gateways to hell

Mine pees into the storm drains near my apartment and they look exactly like those grates. He'll run for them every time. He's not the only one. Plus, when it rains, all the dog piss from the streets rains into them. Or when the street cleaners hose the sidewalks.
