         The Humane Society of the United States is the nation’s largest animal protection organization. It was rated the most effective by its peers. Since 1954, The HSUS has been fighting for the protection of all animals through advocacy, education, and hands-on programs. "We confront national and global cruelties through major campaigns targeting the barbaric practices of dogfighting and cockfighting; abusive puppy mills where dogs are treated not like family but like production machines; the worst cruelties of factory farming in modern agribusiness such as confinement of animals in crates and cages; inhumane and unsporting hunting practices such as "canned hunts" of captive exotic animals; the suffering of animals in experimentation, including chimpanzees and pets; the slaughter of American horses for export to foreign countries where horsemeat is considered a delicacy; and the clubbing of baby seals and other animals for the commercial fur trade."
