The Humane Society of Missouri Volunteer Program helps fulfill the organization’s mission of providing second chances to animals that have been abused, neglected or abandoned. 

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

No matter what volunteer opportunity you select you will be helping provide second chances to animals in need.

Is volunteering at the Humane Society of Missouri right for you?

We hope so! Applicants must ensure a six-month volunteer committment and be at least 18 years of age. Regular volunteer opportunities are available at each of our St. Louis area shelters - Chesterfield Valley, Maryland Heights and St. Louis City, near Forest Park - and at Longmeadow Rescue Ranch in Union, Missouri.

Currently, the Humane Society of Missouri is unable to provide service hours for school or organizational credit. Limited court ordered opportunities are available only at Longmeadow Rescue Ranch in Union, MO (about 1.5 hours west of St. Louis). For those under the age of 18, we encourage your involvment with our Education Department
