Service dogs assist people with a wide range of disabilities, not only vision loss. Meet Diana, a person living with CMT, and her service dog Marvin. The two were matched through Canine Companions, an organization that trains and places service dogs at no cost to recipients.

In this feature, Diana shares how Marvin came into her life and the practical ways he supports her day to day. The video also includes a special guest appearance by Jim and Elsa.
