Dogs of war get PTSD as often as humans

Here's an article I found on Ohmydog.com that I found interesting and useful.  It would stand to reason that these dogs would show some traumatic effect of being in a war zone and being surrounded by war activities.
I don't understand why we insist that animals are so terribly different from humans.  They are not.  We all come from the same biological tree.  Life is life.  Please read this article and let me know what you think.

Just like their human counterparts, dogs in the military can suffer the symptoms of post traumatic stress disorder — and they’re doing so at a rate nearly as high as humans.

By some estimates, more than 5 percent of the approximately 650 military dogs deployed by American combat forces are developing canine PTSD, according to a report in yesterday’s New York Times:

“ … (T)he concept of canine PTSD is only about 18 months old, and still being debated. But it has gained vogue among military veterinarians, who have been seeing patterns of troubling behavior among dogs exposed to explosions, gunfire and other combat-related violence in Iraq and Afghanistan.”

Of the dogs who show symptoms, about half are likely to be prematurely retired from service, said Walter F. Burghardt Jr., chief of behavioral medicine at the Daniel E. Holland Military Working Dog Hospital at Lackland Air Force Base.

The Times article, accompanied by the beautiful photograph above, reported that dogs show the symptoms in different ways, much like humans with the  disorder. They may become hyper-vigilant, undergo temperament changes, turn aggressive with their handlers, or start becoming timid and clingy, avoiding areas that they had once been comfortable in.

Most crucial of all — at least as the military sees it — they can also stop doing the tasks they’re being relied on to perform.

“If the dog is trained to find improvised explosives and it looks like it’s working, but isn’t, it’s not just the dog that’s at risk,” Dr. Burghardt said. “This is a human health issue as well.”

The number of  dogs on active duty has risen from 1,800 in 2001 to about 2,700. The training school headquartered at Lackland prepares about 500 dogs a year for deployment.

Combining all branches of the armed services, more than 50 military dogs have been killed since 2005, the article reported.

Dr. Burghardt uses videos to train veterinarians to spot canine PTSD, such as this one of a dog that, while he has no problem inspecting a car, refused to go inside a bus or a building.

Treatment of dogs suspected of having the disorder can range from taking them off patrol and allowing them to just be dogs for a few days to ”desensitization counterconditioning,” which involves exposing a dog, in increments, to sights or sounds he’s reacting nervously to and rewarding him when he doesn’t react.

Dogs that do not recover quickly are returned to their home bases, and those that continue to show symptoms after three months are usually retired or transferred to different duties, Dr. Burghardt said.
