The Hinsdale Humane Society's volunteers contribute in a variety of ways, including:

• Dog walking
• Brushing, playing with and cuddling cats
• Greeting the public as receptionists in person and on the phone
• Providing pet therapy by visiting nursing homes and retirement communities, and by having volunteers and their own Delta-certified dogs visit schools and libraries where children read to the animals
• Providing foster care for animals that are too young to be placed for adoption, pregnant cats or dogs, sick or injured animals, and adult dogs in need of socializing or acclimation to a home
• Helping out with special events and fundraising, including the Pet Walk
• Visiting schools to talk about the humane society, by helping to conduct the summer camp and by giving tours of the shelter.
• Maintaining and updating the shelter's website.
• Taking adopted animals to a local vet for spay or neuter surgery.
• Delivering pet foods and supplies to the local food pantry for needy families with pets.
• Gardening around the shelter

Prospective volunteers must attend an orientation program, including children and adults who will be volunteering together. There is a $25 application fee to volunteer.

Volunteers between the ages of 12 to 15 must be accompanied by an adult, who will volunteer with them and may only work with cats. Young adults, aged 16 or 17, can volunteer by themselves with parental permission, to work with cats and some dogs. Volunteers 18 and older may participate in any of the programs.
