Research to prove dogs relieve stress
Research is being carried out to scientifically prove that specially-trained dogs help heal stress related conditions, such as post-traumatic stress disorder (PTSD).
The US government's Department of Veterans Affairs has ceased funding canine placement programmes as there is currently no scientific evidence that it medically benefits veterans.
For this reason, the US military's top medical research centre, the National Intrepid Center of Excellence, is carrying out tests to prove the theory that these specially-trained dogs have a positive effect.
The scientists say these dogs can reduce the stress-hormone cortisol, they can reduce pain levels, and they can increase wellness in personal relationships.
Seamus is a service dog that has helped his owner cope after the mental and physical scars of the war in Afghanistan, including two years of facial reconstruction.
He is trained to act as a physical barrier when his owner feels overwhelmed by crowds, he wakes her from nightmares and keeps her calm.
"This dog is more therapeutic to me than any medicine, any therapist… He just filled a very, very, very big void," she said.
Abbie, who is only a few months old, is being trained by the Warrior Canine Connection. She has been specially-bred to become a service dog, both for her temperament, and for her ability to transmit oxytocin - a chemical that calms the feeling of stress.
The Warrior Canine Connection trains dogs and veterans together, and welcomes the research.
"We believe [specially-trained dogs] may prove to be the most effective non-pharmaseutical intervention that we can offer to our service members," said Meg Daley Olmert, who works at the connection.
RUMA CA&E has extended the deadline for its online survey into vaccine availability.
