Gus was a lucky dog. Injured and abandoned, he could have become another of the 7 million animals euthanized every year. Then Stephanie Williams entered the picture. A successful journalist, she had been diagnosed with late-stage breast cancer at the age of 30. On medical leave and living alone, she wanted a warm four-legged companion. When she saw Gus's soulful eyes and goofy grin, it was love at first sight: she would rescue him, and he would return the favor. Just Gus is about how much one dog did to make a dying woman happy — giving tireless love, comfort, and support. This extraordinary story shows how one dog brought joy and hope to a woman's last days.
