Join Our Volunteer Force!

Whether you have all day or just a few hours, we are always in need of volunteers. You can help us make a lasting difference in the lives of the 350+ cats and dogs we care for every day and you will get to work with some very dedicated and passionate people who care about the welfare of animals as much as you do. Whatever your interests might be, we are sure to have something rewarding for you to do. Individuals and groups are welcome to volunteer regularly or on an “as needed” basis helping with special projects and events both at the shelter and at off-site events.


Brushing, interactive play sessions, being a “quiet time” companion, 10+ minutes of snuggling and petting.


Walking, general socialization, being a “quiet-time” companion, 10+ minutes of petting and massage.


Cat care, cleaning, feeding & socializing at our satellite center at the  Chesterfield PetSmart.


Become a part of our team by fostering a dog or cat in need.


Help at our off-site adoption and awareness events and fundraising events.


All it takes to get started is a completed application and participation in a brief orientation.  Volunteers must be at least 13 years old.  Volunteers between the ages of 13-15 will need to be accompanied by a parent or adult (age 21 or older.) Click here for our Volunteer Application and agreement , once completed, email it to .

Once your volunteer application and agreement have been reviewed by our staff, you will be contacted by phone or email with upcoming volunteer orientation dates. There is a nominal one-time $20 fee to help cover training costs. With this, you will receive a volunteer t-shirt that is to be worn while volunteering at Open Door.

PLEASE NOTE: Open Door also accepts Community Service volunteers (i.e. those court ordered to work for a non-profit as part of their sentence) or those who need limited volunteer hours for other reasons.  Please call our office for more information on this program at 636-671-3643.

If you’re under 13 years old, there are still many ways you can help:

  1. Organize a collection drive for pet food and supplies – get creative by hosting a movie night or ice cream party for your friends, with a shelter “wish list” item as admission.
  2. Start a fundraiser, like “Pennies for Puppies” or “Coins for Kitties,” at your school. Make it a competition among classes, grades or clubs.
  3. Start a dog-walking or pet-sitting service in your neighborhood and donate the money you raise or use the money to buy supplies for the shelter.
