The Humane Society of the United States is an American nonprofit organization that focuses on animal welfare and opposes animal-related cruelties of national scope. It uses strategies that are beyond the abilities of local organizations. It works on issues including companion animals, wildlife, farm animals, horses and other equines, and animals used in research, testing and education. As of 2001, the group's major campaigns targeted factory farming, animal blood sports, the fur trade, puppy mills, and wildlife abuse.
The HSUS is based in Washington, D.C. and was founded in 1954 by journalist Fred Myers and Helen Jones, Larry Andrews, and Marcia Glaser. In 2013, the Chronicle of Philanthropy ranked HSUS as the 136th largest charity in the US in its Philanthropy 400 listing. Its reported revenue was US$129 million and net assets US$215 million as of 2014.
HSUS pursues its global work through an affiliate, Humane Society International, which listed staff 17 nations for 2013. Other affiliated entities include the Doris Day Animal League, and the Fund for Animals. Together with the Fund for Animals, HSUS operates animal sanctuaries in five US states.
HSUS does not run local shelters or oversee local animal care and control agencies; it promotes best practices and supports such entities throughout the country with a range of services.
