Anderson, the honorary chairman of People for the Ethical Treatment of Animals, was among those walking the dogs at a news conference Monday at New Orleans' City Park.
Since the April 20 drilling rig explosion that sent millions of gallons of oil spilling into the Gulf, some southeastern Louisiana animal shelters have reported large increases in the number of pets brought in. Many are brought in by people who have lost jobs or income because of the spill.
The shelter in coastal St. Bernard Parish reported bringing in 117 animals in June, far more than the 17 reported in June 2009.
