Dogs: A medicine for mental health problems?

Charles Hernandez, 49, credits his dog Valor for helping him cope with PTSD.

Story highlights

  • Psychiatric service dogs help people with mental disorders
  • Emotional support animals comfort people with disabilities
  • 'Not all wounds are visible,' says Sgt. Charles Hernandez
His name is Valor. He's half Labrador retriever, half Great Dane, and goes everywhere with Sgt. Charles Hernandez. But Valor is more than a pet -- Hernandez considers the dog a personal physician.
When Hernandez was having seizures, Valor would nibble on the side of Hernandez's leg before the veteran realized anything was wrong. And the dog pulls him away from conflicts and jumps on him during anxiety attacks to calm him down. In combination with medications, Hernandez says the dog has helped his symptoms of post-traumatic stress disorder.
"I'm alive again," says Hernandez, 49, of the Bronx, New York, now retired from the U.S. National Guard. "What keeps me going is my dog."
A growing number of Americans are getting dogs for mental health needs, experts say. In the case of psychiatric service animals, such as Valor, they are trained specifically to help people with mental illnesses, in much the way seeing-eye dogs are taught to help to blind people.
PTSD in returning veterans is a major reason for the increasing demand for these dogs, said John Ensminger, a New York attorney and author of "Service and Therapy Dogs in American Society."
Unlike guide dogs for people with more obvious physical disabilities, there's a lot of gray area regarding who gets to have a dog accompany them to places -- from restaurants to stores to airplanes -- where animals are usually not allowed.
Why people get psychiatric service dogs
There's pretty good evidence that in some people, interacting with pets produces biochemical changes in the brain, says Hal Herzog, professor of psychology at Western Carolina University.
"In a way, we could all use a psychiatric service or therapy dog because of the incredible amount of stress that we're all under," says psychiatrist Dr. Carole Lieberman, author of "Coping With Terrorism: Dreams Interrupted."
Caring for a pet helps people become less frightened, more self-sufficient and secure. It takes the attention off their own fears, she said. Through owning a pet, you can "prove to yourself that you can take care of another living creature," she said. It "reassures you that you can take care of yourself."
Several categories of dogs that provide care to people with mental health issues have arisen, as the organization Heeling Allies describes:
The first is psychiatric service dogs, which is where Valor falls. These are individually, intensely trained dogs for people with mental disabilities. The Psychiatric Service Dog Society has extensive information about these dogs and how to get a dog trained. Heeling Allies calls them "mental health service dogs" because of the stigma associated with the term "psychiatric."
Then there are emotional support dogs, which provide comfort and motivation to people with disabilities. They may be taken on planes and live in housing situations where animals are not usually allowed, with proper documentation.
Finally, there are therapy dogs, which help a large group of people. For instance, Ensminger's dog Chloe is a therapy dog, and he voluntarily takes her to hospitals to comfort patients.
