You must be 15 to volunteer at the Domestic Animal Shelter (DAS), but I'm not sure for the Humane society.
It depends on where you live, so call your local humane society and ask.
In south Tampa 16 to voluteer or work there.
I think most require you to be 18 or have an adult/parent with you for insurance reasons.
Their website does not offer this information. They have a contact page, you could e-mail them and ask. http://www.odessahumanesociety.org/contact.htm
