Japan Earthquake Caused Long-Lasting Stress in Dogs


Family dogs caught up in the Japan earthquake of 2011 and subsequent nuclear disaster at Fukushima showed signs of stress not inconsistent with PTSD long after the events, a new study finds.

The research compared abandoned dogs rescued from Fukushima with non-disaster affected dogs abandoned in 2009 and 2010, before the earthquake. The dogs that lived through the disaster had stress hormone levels five to 10 times higher than the dogs that were simply abandoned or found as strays.

"Long-term care and concern regarding the psychological impact of disasters appears necessary in humans and companion animals," the researchers wrote today (Oct. 11) in the journal Scientific Reports.
