Can dogs sense the supernatural ?



Can dogs sense the supernatural?
STUDIO TEC/amanaimages/Corbis
Whether folklore or fact, many of us would like to believe that our dogs can detect unexplained or invisible presences, guided by a canine sixth sense. It's exciting, and comforting, to think a favorite dog is sensitive to a departed relative or friend.
But hard evidence of dogs' extrasensory perception is elusive and anecdotal. The 2009 book "Tails of the Afterlife," by Peggy Schmidt, chronicles multiple instances of unexplainable actions by dogs who apparently interact with something, or someone, unseen. For instance, she writes about a woman named Del Johnsen who left seven dogs and six cats when she passed away. Numerous witnesses believe she still visits her pets daily, and report seeing the animals suddenly gather in one spot, cats arching their backs and purring, dogs flopping over for a belly rub, wriggling in enjoyment, all of them sitting at attention and staring into the air before resuming their own activities. And Schmidt says her own Jack Russell terrier Pixie has repeatedly reacted to ghosts present in local buildings rumored to be haunted.
But your pet's so-called sixth sense may simply be the result of his keen hearing, exceptional nose, and a dog's eye view on the world that allows him to sense small movements that escape our attention. A dog's senses are keener, and different, than ours: His eyes detect more delicate movements; his sense of smell is 1,000 to 10,000 times more sensitive than a human's. He can hear much higher frequencies, and at four times the distance of a human with normal hearing.
Wild and domestic animals, including dogs, seemed to sense the impending Indian Ocean tsunami in 2004, displaying their distress with behavior changes and vocal warnings, and either ran for cover or refused to go outside. Some experts believe they could sense vibrational changes on land from impending the earthquakes before humans could.
Dogs' heightened sense of smell is credited with their ability to detect some cancers in humans. Service dogs who aid seizure-prone people are alert to subtle shifts in body smells and dilated pupils, signs that enable the dogs to warn their owners of a looming attack.

Hello ! I'm dingo !


The dingo is legendary as Australia's wild dog, though it also occurs in Southeast Asia. The Australian animals may be descendents of Asian dingoes that were introduced to the continent some 3,000 to 4,000 years ago.

These golden or reddish-colored canids may live alone (especially young males) or in packs of up to ten animals. They roam great distances and communicate with wolf-like howls.
Dingo hunting is opportunistic. Animals hunt alone or in cooperative packs. They pursue small game such as rabbits, rodents, birds, and lizards. These dogs will eat fruits and plants as well. They also scavenge from humans, particularly in their Asian range.
Dingoes breed only once a year. Females typically give birth to about five pups, which are not independent until six to eight months of age. In packs, a dominant breeding female will kill the offspring of other females.
Australia is home to so many of these animals that they are generally considered pests. A famous "dingo fence" has been erected to protect grazing lands for the continent's herds of sheep. It is likely that more dingoes live in Australia today than when Europeans first arrived.
Though dingoes are numerous, their pure genetic strain is gradually being compromised. They can and do interbreed with domestic dogs to produce hybrid animals. Studies suggest that more than a third of southeastern Australia's dingoes are hybrids.

Alpha dogs

Dogs are trained for specific in-the-field jobs including sniffing out bombs, recovering cadavers, protecting police and military, enforcing anti-terrorism initiatives, locating missing persons, detecting forensic evidence and discovering hidden narcotics.anti
While these alpha dogs are often a Working Group breed, not every German Shepherd is a solid candidate. They must demonstrate the right drive, disposition, social skills, and nerve strength to handle the challenges that may come their way. Working dogs rise to the task, despite noise and fatigue. These brave animals are known to ignore personal injury – like cuts, scrapes and open wounds – in the line of duty. They not only persist through extreme temperatures but, with restricted scent, can successfully identify the odor of a cadaver.
According to Ann Christensen, National Association for Search and Rescue (NASAR) Canine Committee Chair, working dogs will persist despite rain, wind, lava rock, hot pavement, crowded cities and unstable buildings in order to complete the task at hand.
Canine Training
NASAR uses a lot of the same training methods that law enforcement might employ when teaching a dog to detect narcotics or explosives. "First, the dog is taught to recognize the target odor," Christensen says. "Then it is taught a final response or indication so the dog can tell the handler when it's been located. Training works on teaching the dog to search in various environments and around multiple distractions without losing focus." While many civilians train dogs with food rewards, Christensen prefers to reward with a toy, game of tug, or retrieve when they find what they are trained to locate. "Civilian handlers normally plan on about 500 hours of trained to get a dog trained, certified and ready for deployment," she explains. "But experienced trainers can do it in less time." Search and rescue dog teams are dispatched across the globe, with multiple teams throughout the United States and Canada.

Vohne Liche Kennels, a full service K-9 training facility founded by United States Air Force Senior Master Sergeant Kenneth Licklider two decades ago, has trained police and military service dogs for more than 5,000 law enforcement and government agencies. They train their dogs on a 600-plus acre property in Indiana, complete with an obstacle course and workout gym. Off-site training sessions include field trips to hotels, schools, impound lots and jails.

"Obedience is on and off lead to heal, sit, stay, come and down," says Licklider, of VLK training methods. Handlers maintain full control of the dog at all times, and use positive motivation techniques (like a toy) as an associate reward. They designed agility training to increase the animal's confidence in a myriad of environments, and apprehension is based on five phases of control. "Tracking [training] is based on following a combination of human skin cells and disturbed vegetation," Licklider explains. "We begin by tracking footsteps, but gradually encourage the dog to trail the suspect lifting their head, utilizing both ground and airborne scent. All substance detection is imprinted the same way with the dogs learning to locate a particular scent then respond passively. Building and Area searches teach the dogs to locate a suspect using airborne scent in a confined area whether it be inside a building or within a cordoned off perimeter."
Dogs in the Field
Kathy Holbert of West Virginia took her personal dog, Strega, as a civilian contractor to Iraq and Afghanistan from 2009-2010. Strega was one of the few human remains detection dogs, tasked with trying to recover missing United States military and civilians. Led by the promise of 'no one left behind,' Holbert and Strega entered into difficult and dangerous situations.
"The most memorable mission was a water search in the Morghab River, near the Turkmenistan border in Afghanistan, where two paratroopers had drowned trying to recover a miss[ed] drop of supplies," Holbert shared. "The recovery efforts were in a highly volatile area, where several other deaths had occurred trying to make recovery. One victim was recovered by a well-trained team of British divers before Strega arrived, quite a bit away from the entry point. The army command wanted to expand the search area based on that recovery, which would have exposed our troops to more danger." But Strega alerted on a hydraulic boil, and her consistent and confident alerts ultimately changed the search direction, and the diving team recovered the victims within days. Had they extended the search area as originally planned, the searchers would have been exposed to greater dangers – Strega's training and mission experience were a life-saving asset to the search and rescue team. "It is rare that a dog trained to find the dead ends up saving the living, but I feel that is exactly what we did there," says Holbert.
One Vohne Liche-trained canine located a missing three-year-old child in a cornfield during the freezing winter after all the other searchers had given up, and ultimately saved the child's life, while another one alerted military to the presence of explosives just prior to an assault team going through a door, saving the entire squad.
In a new series on the Nat Geo WILD, Alpha Dogs, camera crews follow Ken Licklider and his handlers as they work tirelessly to train dogs for police and military personnel across the globe.

Why the Dog Show Winner Looks Like a Monkey

Sharon Jacobs
Published February 16, 2013
Standing less than a foot tall and easily cradled in one of trainer Ernesto Lara's arms, Banana Joe made big news for a small dog when he became the first affenpinscher to win the Westminster Kennel Club dog show on Tuesday.
His short stature and flattened face might not make Banana Joe look like a typical winner: The name "affenpinscher" is German for "monkey terrier," and its mug is definitely simian in appearance. Now this lesser known breed is basking in the spotlight, monkey face and all. (Read "How to Build a Dog" in National Geographicmagazine.)
Why the Flat Face?
People like dogs whose faces kind of look like people, with a squished-in nose and forward-facing eyes: Pekinese, bullmastiffs, and affenpinschers, to name a few. "It's mimicking the way humans appear," said Jeffrey Schoenebeck, a research fellow at the National Institutes of Health who has analyzed the development of shortened canine snouts. Several centuries ago, breeders probably sought out parents with a flat face. (Genetics note: Gene BMP3 likely contributes to a flat face in toy breeds.)
And so Banana Joe's mug reflects centuries of genetic manipulation. There's no advantage for the dog, Schoenebeck notes, except that humans would crave it more as a companion. (Related: Gallery of Dog Pictures.)
What About That Tongue?
Banana Joe sticks out his little pink tongue a lot. Maybe more than your run-of-the-mill canine. The reason may be the flat face. "There's probably less room in their mouth" for the tongue, said Schoenebeck. "It's hanging out."
Why so Small?
"The Affenpinscher comes from a terrier background," explained NIH senior staff scientist Heidi Parker, and like all terriers, it was bred to chase. The early affenpinschers' specialty was hunting down rats and other vermin for its owners. Breeding for a small size came later, as ladies started bringing affenpinschers into the home as lap dogs-and to keep away vermin that might otherwise hide in corners or under long skirts. Today's affenpinschers are in the 6-to-13 pound (3-to-6 kilogram) range.
But the dog's size hasn't given it an inferiority complex. "Most of these little guys do not realize they're as small as they are," Parker says. Toy dogs have been known to chase birds and other animals that rival them in size.
What Comes After Westminster?
Dog lovers may crave an affenpinscher. And that could cause problems if breeders try to produce more pups.
"You'll see some breeds go through sudden explosions, where they'll go from small numbers to really large numbers," says Parker. "Usually that means an increase in genetic diseases." There aren't a lot of potential parents for a purebred litter, so the odds of inbreeding, and its related diseases, go up.
And What About Banana Joe?
Now that he's made us aware of his breed, Banana Joe will retire from competition and live with his Dutch owner, free to fulfill his heritage as a lap dog.
