When a parent returns from military service with an invisible wound, a service dog can be an effective tool in helping live with Post-Traumatic Stress (PTS) or Traumatic Brain Injury (TBI). However, a service dog is different than a family pet and this can be difficult for younger children to understand. Written by a clinical specialist working to help veterans with PTS and the president and CEO of American Humane, the country’s first national humane organization that also trains dogs in need of forever homes, this book is designed to help the children of veterans diagnosed with PTS or TBI understand the role of a service dog and how s/he will help their family.
