Tenino was an adult female wolf, born in the wild and placed into captivity at 1 year of age because of her participation in livestock depredation. Her method of capture, well documented, involved being darted twice by helicopter and translocated twice. This method of capture would have exposed her to the 2 factors that are important in the etiology of posttraumatic stress disorder in humans: uncontrollability and unpredictability. In a case study we conducted, Tenino displayed symptoms that were similar to those of humans with posttraumatic stress disorder. These symptoms included hypervigilance, exaggerated startles, generalized fear, avoidance, and arousal. She also displayed looking up behaviors that occured during the presence of perceived threats such as a neighboring rancher's gunshots; the keeper truck; some keeper activity; and, occasionally, aircraft. When compared to 3 other wolves, including her enclosure mate, these behaviors were exclusive to Tenino.
