They may have played rival bikers on Sons of Anarchy, but now Emilio Rivera and Theo Rossi are joining forces to spread the word about animal cruelty.

Rivera and Rossi have teamed up with People For the Ethical Treatment of Animals for a new campaign urging dog owners not to leave their pups chained up outside. "You have to bring your dogs inside," says Rossi in the PSA. "If you don't want to be outside in the heat, if you don't want to be chained to the side of something with no water...
