When disaster strikes, man’s best friend is often there, working on the front lines and behind the scenes of rescue efforts, helping people cope with trauma and loss.
"They help people relax and calm down," Tim Hetzner, president of the LCC Comfort Dogs, told ABC News.
Lutheran Church Charities (LCC) sent a team of dogs and handlers to Dayton, Ohio, to give support after this weekend's mass shooting where nine people died. Methodist Healthcare in San Antonio sent dogs to El Paso, Texas. They are providing support to first responders after the weekend's mass shooting where 20 people were killed and 26 more were wounded. The dogs will visit first responder stations as well as hospitals in the city, KSAT reported.
"The rate of suicides by first responders—firefighters, paramedics, law enforcement—has escalated from one every seven days to one a day," Methodist Health Systems said in a news release. "These dogs can reach places in the heart no human can."
Last fall, LCC dispatched a team of dogs and handlers to California in response to the Camp Fire, the state's deadliest wildfire. The dogs provided much needed love and comfort to thousands of evacuees at various shelters and churches. The organization said the dogs helped the residents "reduce their stress, share their worries and pray with them." The dogs also visited first responders who worked around-the-clock battling the wildfire.
The dog brigade has also helped in the aftermath of some of the worst disasters in recent history, including the Marjory Stoneman Douglas High School shooting in Parkland, Florida, the Las Vegas shooting in 2017, the Orlando Pulse nightclub shooting in 2016, as well as the Boston Marathon bombing in 2013 and the Sandy Hook shooting in 2012.
The LCC K-9 Comfort #Dogs were invited to and will be present at #StonemanDouglasHighSchool today when the students return to class. We lift up the students, the teachers, the faculty, and the entire community in our prayers.— LCC K9 Comfort Dogs (@K9ComfortDogs) February 28, 2018

While medical professionals tend to the survivors, four-legged caretakers look after everyone else — from family members who lost loved ones to first responders and other members of a community in shock.
"Your blood pressure goes down when you pet a dog, you feel more comfortable, and people end up talking," Hetzner said. "They're good listeners, they're non-judgmental, they're confidential."
Truly man's best friend
When disasters occur, dogs do much more than just aid search-and-rescue missions. They’re often there to provide a source of comfort for us in ways that only an animal can.
In an interview with American Thinker, Debra Tosch, executive director of the Search Dog Foundation (SDF), explained how her search and rescue dog Abby was able to console a firefighter at Ground Zero. "When someone was found, work would stop, and I watched as the tears rolled down the firefighters' faces. I remember one firefighter who hugged Abby and buried his face in her neck after just finding out a fellow firefighter was found," she said.
Research shows that petting dogs can lower anxiety, regulate breathing and decrease blood pressure, and a Japanese study found that simply looking at a dog can increase levels of oxytocin, a chemical released by the pituitary gland that’s associated with human bonding and affection.
But while the firefighter may have found comfort in Abby’s presence, was the dog able to empathize? Research says it’s very likely.
A 2012 study at Portugal's University of Porto found that dogs yawn even when they hear only the sound of a person yawning, providing strong evidence that dogs are able to empathize with us.
And a study at the University of London Goldsmiths College found that dogs comforted people — both their owners and strangers — when the person pretended to cry.
"I think there is good reason to suspect dogs would be more sensitive to human emotion than other species," Deborah Custance, co-author of "Animal Cognition," told Discovery News. "We have domesticated dogs over a long period of time. We have selectively bred them to act as our companions. Thus, dogs that responded sensitively to our emotional cues may have been the individuals that we would be more likely to keep as pets and breed from."
Super sniffers: The power of the nose
Experts estimate that one search and rescue or SAR dog can accomplish the work of 20 to 30 human searchers. Because of these unparalleled abilities, the number of trained SAR dogs has been rising across the United States.
Dogs make efficient searchers due to their superior vision, hearing and sense of smell. A dog’s nose is about 100 times more sensitive than a human nose, and SAR dogs are trained to locate human scents amid countless other smells. They track our scents by the 30,000 to 40,000 dead skin cells we drop every minute.
"Dogs aren’t miracle workers, but their noses are so precious," said SDF founder Wilma Melville. "They can find those people who survived a horrific ordeal."
Air-scent dogs are trained to work in specific types of terrain. Some search in wilderness settings while others search urban environments, which often can involve scouring collapsed buildings.
Because they must navigate unstable terrain, urban SAR dogs are some of the most highly trained canines. The only national standards for such dogs are the Federal Emergency Management Agency's certification standards for urban disaster work. Currently, 243 dog-handler teams in the U.S. have this FEMA certification, according to the Search Dog Foundation.
In addition to air-scent dogs, there are dogs taught to seek out both skin cells and the smell of human decomposition. During major disasters, such as the 1995 Oklahoma City bombing and the 2001 collapse of the World Trade Center, both air-scent dogs and cadaver dogs were used to search for people.
This caused problems for SAR dogs because they became discouraged when they found only dead bodies. At both Oklahoma City and Ground Zero, handlers hid in rubble so that dogs could occasionally find a living person. The dogs’ desire to elicit a response from a found person may be a result of their training, which involves seeking feedback and rewards, but experts say it could also speak to a deeper connection with humans.
