How old do u have to be to volunteer at the humane society of odessa in Texas?

16 and up

It depends on where you live, so call your local humane society and ask.

You must be 15 to volunteer at the Domestic Animal Shelter (DAS), but I'm not sure for the Humane society.

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.
