    The mysterious science behind lifesaving dogs

    Firefighters rescuing a trapped infant inside a burning house in Baltimore, Maryland, last summer reportedly found an unbelievable sight. Eight-month-old Viviana was severely burned, but alive. Inexplicably, Polo, the family dog, was found laying on top of the baby, apparently saving her life, according to CNN affiliate WBAL. Sadly, Polo didn't survive the fire.

    In Atlanta in 2014, a German shepherd saved the lives of two family members during a road-rage confrontation. Witnesses said an armed driver followed a family to a strip mall and started shooting, prompting the family dog in the car to jump into the line of fire, shielding a child and a woman. The dog later died.

    In Connecticut in 2012, a family dog awoke parents in the middle of the night, apparently warning that their infant daughter had stopped breathing, CNN affiliate WFSB reported. They were able to revive her and she ended up being OK.

    Stories like these grab headlines and riase the question: What motivates family dogs to protect their human caretakers? What's going on in the hearts and minds of our pets that can prompt them to make the ultimate sacrifice?

    Annika Huber, a doctoral student at Switzerland's University of Bern Veterinary Public Health Institute who has studied dog behavior said it's possible dogs are motivated by human-like feelings that allow them to empathize with us.

    In fact, there arestudies that suggest dogs have the ability to feel empathy toward humans. One experiment found a connection between empathy and "contagious yawning" -- that phenomenon when someone in the room yawns, and that, in turn, makes you yawn -- so the dogsstarted yawning when a human was yawning nearby.

    This"may indicate that dogs possess the capacity for a rudimentary form of empathy," the study concluded. Ramiro Joly-Mascheroni, co-author of the study, acknowledged the dogs may have been simply yawning because they were tired or stressed. But"humans don't fully recognize others' feelings until age 4 or 5," he added.

    But we are closer to being able to find out. "Years ago, we would not have expected to be able to study and speak about empathy in animals," said Huber. "This was a capability reserved for humans." Now, it's an idea that Huber and other scientists are taking seriously and looking at with great interest.

    What happens when you look into your dog's eyes

    Dr. Brian Hare, founder of the Duke University Canine Cognition Center, said canines have learned to bond with us and -- to a certain extent -- "read our minds" like no other animals can.

    "What is extraordinary is that dogs are so close to us -- and so much a part of our lives -- that they sometimes happen to be in the right time and place, and whether intentional or not, manage to save lives."

    hey bond with us -- in some ways like children bond with their parents. This bond has been proven through a physiological phenomenon known as the "oxytocin loop."

    Here's how it works: When babies look into their parents' eyes, a hormone is released in both the baby and the parent. The hormone, called oxytocin, can make us feel good, said Hare. "It creates this oxytocin loop that encourages us to protect and care for our babies."

    Hare said something similar happens between humans and dogs. When your dog stares into your eyes, your oxytocin rises. When you stare into your dog's eyes, their oxytocin rises.

    "Dogs have basically hijacked this pathway that was meant to be between us and our kids," Hare said. "So when your dog is just staring at you for no apparent reason, they don't necessarily want anything. They are just hugging you with their eyes."

    Other ways we connect with dogs

    True emotional bonding between humans and dogs, said Huber, would be difficult to prove scientifically. "Obviously, with humans you can ask them," she said. "But with dogs, it's really difficult to find valid indicators of an emotional state."

    Researchers have been using MRI technology to study dogs' brains to see if they respond to human voice cues. In images showing dogs' brain activity, specific parts of dogs' brains lit up when the dogs heard human voices with positive vocalizations.

    Another study indicated that dogs can tell the difference between various emotional human facial expressions.

    Huber believes some dogs' personalities may be more sensitive to humans. She remembers that years ago her owndog, Louis, "was quite special in terms of picking up emotional states." Her mother called him her "mirror," she said.

    Louis only seemed to respond excitedly to Huber when she was under stress. For example, during exams while sitting quietly at her desk, Louis would often jump on her, barking and sometimes destroying objects in the room. But when Huber was not stressed -- sitting quietly at her desk -- Louis did not act out these behaviors.

    Huber, who has published her own research on this topic, said it's possible some dogs respond to what she describes as, "very subtle signals of our emotional states, potentially those that may even not be obvious or conscious to ourselves."

    Her colleagues at the University of Bern conducted a separate study of hypersensitivity in dogs. It found that so-called "canine sensory processing sensitivity" (c-SPS) is a measurable personality dimension.

    And, it may be genetic.

    But there are still a lot of unanswered questions surrounding the real reasons why some family dogs lay down their lives for humans.

    For example, we don't know why Polo saved little Viviana's life in that burning house in Baltimore last summer. At least for now, there's not really a scientific answer that would explain Polo's actions, Hare said.

    When dogs attack

    What about the opposite? What drives beloved family dogs to act aggressively -- even attack their owners -- suddenly and unexpectedly? There are multiple causes that could contribute to this. A dog could be suffering from a hidden, painful health problem, for example. Disorders such as hypothyroidism -- when the thyroid glad doesn't produce sufficient amounts of certain hormones -- can increase aggressive behavior in dogs. Another potential factor is fear triggered by a dog suddenly sensing a threat to itself or its environment.

    Also, miscommunication between pets and owners can spark a seemingly sudden attack. "Sometimes, aggression might not have come up as suddenly as we think, but due to a history of the owners not understanding or misunderstanding the dog´s behavior," Huber said.

    For example: a child who repeatedly tries to pet or hug their family dog when the dog may not like to be petted.

    Dogs often show us they don't like our behavior by doing things like freezing, yawning, lip licking or moving away from the child, she said.

    But if the child misunderstands or misses these cues altogether, the potential risk is that the dog will resort to more intense signals -- such as growling or snapping.

    "These are the behaviors we only pay attention to," Huber said.

    Do dogs exhibit 'moral behaviors?'

    Perhaps in the future, Huber said, scientists might intensify their research on other complex capabilities in dogs, in addition to empathy, like "moral behaviors" -- something that has "been thought to be reserved only for humans."

    The more we learn about how dogs think and feel, she said, the more likely it will pose "important ethical questions concerning our treatment of animals" and our obligations to them.

    But if you ask countless dog owners for their opinions, many will tell you they don't need any scientific research to prove to them what they already know: Their dogs love them unconditionally. And sometimes they prove it in ways that seem nothing less than miraculous.

    Funnily enough I had a beer in here last week. The entrance to the churchyard is that alley on the left, the church is right behind the pub.

    I've read that dogs can 'smell' a human's mood from the pheromones we give out, and they are also much more sensitive to the subtle body language we display. Humans are often acting very differently to their actual mood, to conform socially, avoid arguments etc and dogs find this really confusing. For example, hypothetically, my wife may be pissing me off yet I act relaxed and happy for the sake of my daughter. In this case I could noticed the dogs giving me strange looks and acting nervously because maybe they can 'smell' that I'm not happy. They may also pick up on stuff like muttering under my breath and kicking a plant pot, for example.

    One of our dogs always got very upset when she saw me pack for work, she would go off her food and just mope about for a few days. This happened to such an extent I now pack secretly where she can't see me. She still gets upset however and we think maybe she picks up on a few key words I may say in the days before leaving, maybe 'flights', 'taxi', 'bloody work again', etc.
