The Waterfront Development Corp., which also manages the Waterfront Park in Louisville, said pet owners will have an opportunity during a rally Sunday at the entrance ramp on the Kentucky side of the bridge to sign forms pledging to clean up their pets' droppings, The (Louisville) Courier-Journal reported Thursday. Advertisement Officials said the rally, from 1 p.m. to 3 p.m., is intended to promote responsible pet ownership and will serve to inform dog owners that pet droppings on the walkway will be monitored during the coming weeks. They said steps -- including a potential ban on dogs on the walkway -- may be taken if droppings prove to be a problem. The local humane society and the animal services department -- which drew up the pledges that animal owners will be given to sign -- have put their support behind the initiative. Dog owners who sign the pledge will get free T-shirts, officials said.
