Humane Society of Missouri volunteers help fulfill the organization’s mission to provide a second chance for animals that have been abused, neglected or abandoned.

Our volunteers are committed to furthering that mission by supporting our staff, programs and events dedicated to providing humane treatment, improved quality of life and placement into forever homes for the animals in our care.

Volunteer opportunities are available at each of our three St. Louis area shelters - Chesterfield Valley, Maryland Heights and St. Louis City, at Longmeadow Rescue Ranch in Union, MO and from your own home as a Foster Parent. Learn more about each opportunity:

If you are under the age of 18, we encourage you to look into ways to get involved through our Education Department or collecting items on our Wish List to help the shelter animals.

The Humane Society of Missouri strives to be environmentally friendly and primarily utilizes electronic communications and online training. If you are not able to proceed with our online applications, please call 314.951.1577 for assistance.
