You love helping animals.
So do we.

Your generous donation helps us fight animal cruelty wherever we find it. Thanks to you, we’re creating a gentler, more compassionate world for all animals.

We fight for all animals

Together with our supporters, we take on the big fights to stop cruelty before it happens. We’re working to end puppy mills, factory farms, trophy hunts, animal testing and other cruel industries so we can achieve the vision behind our name: a humane society. And we can’t do it without you.

Here are just a few of our biggest fights. With your help, we can win them.

Frequently asked questions


Founded in 1954, the Humane Society of the United States fights the big fights to end suffering for all animals, not just dogs and cats. We work to stop large-scale cruelties such as animal fighting, puppy mills, factory farming and the wildlife trade. Along with our supporters and volunteers, we work to pass anti-cruelty laws, end the extreme confinement of farm animals in cages, stop cosmetics testing on animals, halt cruelty to wildlife and bring veterinary services to pets in underserved communities. Along with our affiliates, we care for tens of thousands animals each year through our rescue teams, direct care programs and sanctuaries. To learn how we put your dollars to work, take a look at our annual reports and financial statements.

You can join the fight in so many ways! Here are a few suggestions.

  • Make sure your pet always wears an I.D. tag.
  • Prepare a disaster plan that includes your pet.
  • Contact local law enforcement if you witness animal abuse.
  • Make sure your pet is spayed or neutered, and consider adopting your next animal—you could save a life!
  • Help stop the export of American horses for slaughter for human consumption—ask your Congressional representatives to support the Safeguard American Food Exports (SAFE) Act.
  • Refine your diet by avoiding factory farmed animal products and including more plant-based options on your plate.
  • Put your skills and talents to work for animals by volunteering with us.

Local humane societies, shelters, rescues and SPCAs are independent entities; they are not run by the HSUS or any other national entity. They have their own policies, governance and operational priorities. We support local organizations in many ways, but we primarily run our own programs to care for animals in crisis and fight the root causes of animal cruelty—large-scale work that’s beyond the scope of smaller organizations and agencies. Read more about how we support local shelters and work alongside them on many crucial issues.
