I think it is important for people to understand why service dogs matter. Service dogs help people with disabilities live with more independence than they otherwise would. They help in ways that those of us who live without disabilities and without the need for service animals can’t fully understand and appreciate. This video, though, provides a window into the life of a person who uses a service dog to interrupt self injurious behavior. If you want to understand how service dogs help, see Danielle Jacobs’ many videos in which she, as she puts it, opens herself, to help others understand mental illness and service dogs.
