The shelter eventually split up Duke and Gizmo, dubbing Duke "rescue only," meaning he would be ineligible for direct adoption by a family. Gizmo, on the other hand, was kept away from Duke in a separate kennel, according to the Chicago Pets Examiner. With the unlikelihood that Duke would be rescued, the shelter scheduled his euthanization.
"Duke was thrown into an isolation kennel because he was trying to protect Gizmo. As Duke sits there cowering in a corner of a dark kennel, he can hear Gizmo crying all the way across the shelter, aching for the comfort of his friend," the Chicago Pets Examiner reported.
