The Humane Society of the United States is the nation’s largest and most effective animal protection organization. We provide hands-on care and services to more than 100,000 animals each year, and we professionalize the field through education and training for local organizations. We are the leading animal advocacy organization, driving transformational change in the U.S. and around the world by combatting large-scale cruelties, such as puppy mills, animal fighting, factory farming, seal slaughter, horse cruelty, captive hunts, and the wildlife trade.
