Dogs Get Combat Stress, Too

Post-traumatic stress disorder doesn't affect only humans: About 5% of the military's 650 combat dogs have canine PTSD, reports the New York Times. The diagnosis itself is only about 18 months old and a bit controversial, but military veterinarians are seeing more and more dogs who can no longer perform duties such as sniffing out IEDS after a harrowing experience.

“If you want to put doggy thoughts into their heads,” says one expert, “the dog is thinking: when I see this kind of individual, things go boom, and I’m distressed.” Some can be coaxed back into training, but many have to return to the civilian world. For good reason: If the dogs are too afraid to do their jobs, it exposes their human pals to risk. (More PTSD stories.)
