For Rescue Dogs,
"Nothing's better than a live
find"
by Catherine Dold
ELBOW BY ELBOW, LIKE A TINY
MARINE, Tasha is crawling across the
dirt. Her task is simple: slither under a pickup truck on the driver’s
side, crawl out on the passenger side. She’s made it halfway, guided by
the enthusiastic calls of her owner, Sue Purvis, who is squatting
in the dirt near the passenger door. Underneath the axle, though, the
black Labrador puppy pauses, looks around and abandons her mission,
scrambling instead toward the tailpipe and out into the sunshine.
Purvis quickly hustles her back to the driver’s side, and again gives
her the command: “Go through!” Tasha drops to her elbows. Purvis
runs around the truck, shouting encouragement. ‘Come on, Tasha!
Let’s go, girl!” This time, Tasha crawls straight across, causing
her owner to explode in praise. Thrilled to have made Purvis so
happy, Tasha wriggles the entire back half of her body in delight.
Tasha’s teammates soon follow: Jazz, an
Australian shepherd; Ranger, a chocolate Lab; and Odie, a mixed breed,
each do a flawless truck crawl. Amid hugs, praise, high fives and
wagging tails, the dogs and their owners then move on to other events in
this doggy Olympics being held just outside Dinosaur National Monument in
northwest Colorado. One by one, the dogs politely walk on leash while a
human at the other end carries an egg in a spoon. They sit patiently in a
beached, rocking canoe while the crazy humans jump in and out. And in a
new twist on the wet T-shirt contest, each dog dashes under a large
tarp with its owner and, after a flurry of flying canvas and wagging
behinds, emerges triumphantly wearing a large, drooly T-shirt that
moments earlier had been on the human.
Two dozen onlookers alternately cheer wildly and try to trip up
the competition. But Tasha’s team proves unbeatable. They trounce
three other teams, sending both the dogs and their human handlers into a
frenzy that rivals the excitement of the real Olympics.
The games are just one portion of an entire weekend
of canine fun. Tasha is also enjoying hikes through the scrubby
Colorado Desert, sleeping under the stars and mingling with more than a
dozen dogs from around the state. How much more fun can a 9-month-old pup
have? What Tasha doesn’t know, though, is that all her activities
have been designed with a deadly serious goal in mind.
Like most of the dogs here, Tasha, Odie and Ranger are
search and rescue dogs in training. Soon, these prancing pups will be
expected to leave their fireside napping spots at a moment s notice and
use their noses to find lost children and adults, track down dead bodies
and locate people buried under avalanches or concrete and debris.
Sue Purvis and the other dog handlers know that people
will expect a lot from their pets. Some will expect miracles. Sheriffs and
tearful parents will count on them to do a job that otherwise could
require dozens of people and many, many hours of work. So they have come
to this remote corner of Colorado for a training weekend sponsored by
Search and Rescue Dogs of Colorado (SARDOC). The humans are practicing
moving through the desert guided only by map and compass, the dogs are
learning how to track human scent, and both are picking up tricks of the
trade from veteran search dogs and their handlers. The session, dubbed a
‘Confidence Weekend,” helps to strengthen the trust between dog and
handler, reinforcing the notion that just about anything ‘Mom” or “Dad”
asks the dog to do is OK, whether it’s fumbling with a T-shirt in the dark
during a practice session or riding a chairlift to the top of a ski slope
or being hoisted through the air to a noisy helicopter while on a rescue.
Tasha has been in training since she was a mere 11
weeks old. Yet it will be at least another nine months before she is
skilled enough to pass the rigorous tests required to become a
SARDOC-certified wilderness search and rescue dog. And that is only the
beginning. “Wilderness certification is like graduating from high school,
the stepping-off point to the rest of the world,” explains Wendy Wampler,
who owns jazz. Purvis and Tasha will need to continually
practice finding volunteer victims, to be ready to go to work day or
night. They might also get specialized training for water or avalanche
rescues, cadaver searches and certification by the Federal Emergency
Management Agency as an urban disaster search team, the hardest specialty
of all.
With lots of practice, Purvis and
Tasha might someday he as good at finding lost people as are Wampler
and Jazz, who have found numerous individuals in their years of search
work. Wampler’s favorite rescue, she says, was the time she and jazz found
a 12-year-old girl named Kendra and her dog, who were lost in the
mountains near Aspen. While camping with her family, Kendra and her dog
failed to return from a solo late-afternoon hike. Searchers from
the sheriff’s department and other campers were unable to find her, and
Wampler and Jazz had been called in at about AM. Starting at the point
where Kendra was last seen, Jazz started following the girl’s
eight-hour-old trail and, just before dawn, led her handler to the edge of
a large field of boulders. “I called out her name again, and this time she
responded,” recalls Wampler. “1 was so relieved.” Kendra was cold and wet,
hut otherwise fine, although she told her rescuers she had panicked
earlier and run blindly through the woods, screaming. “But she’d had the
presence of mind to keep her dog with her, and she finally sat down and
let it keep her warm.’ Last year, Kendra and her parents came to a dance
benefit for SARDOC. In honor of Wampler and her wonderful search dog,
they announced, they had named their new puppy Jazz.
Over the Saturday night potluck supper at Dinosaur, the more
experienced SARDOC handlers give the newcomers a few tips. Get your
dog some earplugs for helicopter rides, they suggest. Always wear cotton
so your clothes won’t melt in case of fire. They also talk about the
traits that can make or break a search dog, including the dreaded “bunny
issue.” Dogs of all types, from pound mutts to standard poodles, are
getting into search work these days, but not all will make the grade. “If
your dog chases rabbits and doesn’t come right off it when called, you may
not have a search dog,” warns Kelly Pontbriand, a veteran handler and the
coordinator of the weekend’s activities. Another handler warns that no
matter how much training they receive, some dogs “can’t find hamburger in
a phone booth.” Bunnies and noses aside, many people drop out because they
didn’t realize that training and maintaining the skills of both dog and
handler can require as many as a thousand hours of work a year, no small
commitment of time.
Early the next morning, Tasha is preparing to take
her first official step toward SARDOC certification—the most basic
trailing test, the T1. To get to this point, Purvis and Tasha
had started their training with simple hide-and-seek games in the woods
near their home in Crested Butte. Tasha, held back by another
person, had watched Purvis run off a few times and was encouraged
to “go find” her. Once she caught on to that game, she watched one of
Purvis friends run off and found her, then did the same with a
stranger. Next, she was faced in the opposite direction while each of
those people ran away, forcing her to rely on following the scent left
behind. Eventually, to orient Tasha to exactly who she was looking
for, Purvis began letting her sniff a scent article, an item of
clothing that carries the unique odor of the “victim.” Repeated week after
week, the training modifies and strengthens Tasha’s natural hunting
instinct, turning searches into a job that Tasha will readily carry
out whenever she is given the command “go find.” Her reward, each time she
finds her quarry, is a hearty helping of praise and play with a
special toy.
“Tasha knows what the routine is now,”
Purvis says as she straps the puppy into her work harness. Kamala
Mirchandani, another handler, is playing victim. She gives Purvis
one of her dirty socks (in a plastic bag to prevent contamination by
other scents) and walks off into a stand of stunted evergreens while
Tasha looks away. When Mirchandani is about 500 feet away and behind a
tree, Purvis gives Tasha a quick snoutful of sock and
whispers “go find” in her ear. Tasha takes off like a little black
rocket, sniffing the ground and homing in on Mirchandani while Purvis
and the test evaluators scramble to keep up. In less than a minute,
Tasha finds her quarry. She has passed her T1 with flying colors.
Ranger, who is nearly a year old, is doing his first
overnight trail at Dinosaur. A howling wind has pushed around the scent
trail that was laid last evening, making Ranger’s job more difficult, hut
when owner Darren Weibler gives him the command, Ranger puts his nose to
the ground and does his job. Weibler follows close behind. “Good boy,
Ranger. Go find her. Go find.” Soon Ranger is just a few feet from the
victim, who returned to the end of her trail this morning, but because he
is relying solely on his nose, he hasn’t detected her yet. No one breathes
a word or takes a step, for fear of tipping off Ranger. Just as he was
taught, Ranger follows the scent on the ground right to the victim, never
once using his eyes. His reward: lots of love and a chance to maul his
favorite purple monster toy.
SUE PURVIS AND DARREN WEIBLER AND THEIR dogs won’t be
paid even so much as a bowl of kibble for their work. Yet each has decided
to commit a significant amount of time, effort and money to search work.
“I’ve finally found my passion in life,” explains Purvis. “Nothing
is more thrilling to me. This work combines everything: spending time in
the woods, spending time with my dog and concern for people.” Wendy
Wampler says, “If someone’s child is lost, we have to find him. That’s
what I’d want for my child.”
It would he nice to think that Tasha and Ranger are
also worried about lost children and track them down to save them from
peril, just like Lassie always did. But these Labradors are doing nothing
more romantic than following trails of dead skin cells. Humans shed tens
of thousands of skin cells every minute, leaving behind a sort of
invisible bread crumb trail that is very obvious to a dog. Those skin
cells, or “rafts,” along with sweat and other body secretions, are
constantly being broken down into their chemical constituents by bacteria.
The gases exuded during those reactions are what give each human a unique
scent. As the rafts leave the body, some settle on the ground, while
others float on air currents. The odor they give off can percolate through
air, water, snow, mud and even porous concrete.
A dog is particularly well suited to detect those scents.
Odor molecules that venture inside the snout of a large dog encounter a
sea of scent-detecting receptor cells—the tissue area of a German
shepherd’s nose, for example, is about 17 times larger than that of a
human’s. Each receptor cell, in addition, has a high number of hair-like
cilia, which very efficiently bond with the odor molecules. The molecules
arrive, “dock in” at the receptors, and the receptors send an
electrical signal along nerve pathways to the brain. “Aha! Scent number
4,765!” A dog’s sense of smell is probably 1,000 to 10,000 times better
than a human’s, says Jim Johnston, director of behavioral research at
Auburn University’s Institute for Biological Detection Systems, where he
studies the ability of dogs to detect explosives and drugs.
‘For dogs, odors are a more important part of the world than for
us,” says Johnston. “They get a lot of information from odors—where other
dogs have been, where the food is.” A dog truly “sees” the world through
its nose. Indeed, giving a dog a scent article to sniff is akin to showing
a person a photograph.
Most SARDOC search dogs begin their training as Tasha and
Ranger did, with nose-to-the-ground trailing. But once they learn the
basics of following a scent, they are usually switched to detecting
airborne rafts. Air scenting allows a dog to find a victim without having
to follow his entire route, and enables it to search a larger area, as
much as a square mile. To the untrained eye, it sometimes looks like
chaos, as Odie demonstrates at another SARDOC training weekend.
On the edge of a grassy field at a Boy Scout camp near Colorado
Springs, Odie is listening to his handler, Steve Howard, the Basalt,
Colorado, fire chief “Are we going to find someone?” Howard asks in a
high-pitched, excited voice as he straps on Odie’s orange search dog vest.
“You bet we are! You’re a smart dog, aren’t you, Odie?” Odie is so excited
to be playing the game again that he can barely contain himself. He often
gets so excited when working, says Howard, that he can’t sit still long
enough to eat. Once Odie is suited up, Howard gives him a whiff of a scent
article. “Go find ‘em!”
Nose high in the air, nostrils wide open, Odie traverses the
field perpendicular to the breeze, searching for just the right scent.
Within seconds he does his own particular style of “alert”—his tail stops
wiggling and stands straight out— which tells Howard that he’s found it.
He then runs to the edge of the field to see how far the scent stretches.
The victim, in a grove of trees upwind, is shedding rafts that, it is
theorized, cover a wider and wider area as the wind carries them away,
like the wake of a boat. Odie runs hack and forth, finding the edges of
the wake, or scent cone, all the while moving toward the source of the
scent, the victim. His traversing takes him over rocky ledges, through
heavy brush and up steep slopes. The wind is particularly squirrelly
today, shifting direction every few minutes, pooling the scent in rocky
hollows and throwing Odie off track. Howard checks the wind direction with
a length of yellow surveyor’s tape tied to his finger and gently directs
Odie to a spot where the dog will have a better chance of picking up the
scent. He won’t lead Odie to the victim, hut be will help the dog to have
a successful training session. Suddenly, Odie lifts his nose higher, makes
a hairpin turn, and takes oil at a clip to where the victim sits under a
tree. He then does a “refind,” racing hack for Howard and freezing in
place when he spots him, as if to say, lye found the source, Steve! Hurry
up and follow me!”

Howard yells, “Show me, Odie! Show me!” and the dog
leads him straight to the victim Odie’s reward: a few minutes of play with
his favorite ripped-up Frisbee and a ride on Howard’s shoulders.
Handlers often comment that they’re “the stupid part of the
team.” It’s true, to some extent. The dogs act primarily on instinct,
sharpened by training. Handlers must learn to put their own instincts
aside sometimes and let the dog do its job. “The biggest problem in
training any team is the handler,” says Andy Rebmann, who once trained
police dogs for the Connecticut State Police and now runs search and
rescue seminars. “We train the dog to become a reliable tool, then
we’re always trying to think for the dog, not trusting the dog to do the
job it was trained to do.” That’s not to say that handlers should sit idly
by waiting for the dog to do a Lassie. They must plan a search strategy,
making sure they cover their assigned area and take into account the
strange things that wind, ram, snow, heat and humidity can do to odors.
‘They must watch their dogs constantly, looking for the most subtle
alerts. (Not all are as obvious as one standard poodle that Rebmann says
jumps several feet in the air.) They must learn how to put together all
the pieces of the search puzzle and find the victim as quickly as
possible. It can be enormous pressure. Based on what a dog does and how
a handler interprets it, search and rescue teams will tear up house
foundations, rappel into deep canyons, send divers into murky waters or
abandon an area, declaring it cleared of victims.
“I doubt myself every time,” says Wendy Wampler, who has been
working with search dogs since 1982 and admits to occasionally asking Jazz
to find her toddler when he is hiding in the house. “I’m always scared
that I’ll choose the wrong search strategy and I won’t find the victim.
That’s why I train so hard. It’s the only way I can live with myself1”
TO THE DISMAY OF SOME PEOPLE, THERE ARE NO national standards
for certification of wilderness search and rescue dogs, even though more
than 150 groups like SARDOC have sprung up in the past 15 years. SARDOC
requirements are among the more rigorous: members progress through three
trailing and four air scenting tests during training, and then must
complete three difficult searches, including finding multiple victims and
searching at night, to be certified. Handlers are expected to he
affiliated with their local search and rescue agency, to be physically fit
and to have first aid and wilderness survival skills. After all, searches
aren’t always conducted in fields of mountain flowers on balmy spring
afternoons. A person with Alzheimer’s or a cross-country skier is just
as likely to he reported missing at 5 P.M. during a snowstorm, leading
to a long, cold night of searching. It is not an easy job.
“It’s tough to arrange day care at 3 AM., says Wampler.
“Sometimes, in the middle of a search, I think ‘What am I doing out here,
I must be out of my mind.’ Then, my dog picks up an alert and it’s all
worthwhile.” Wampler and the 21 other certified SARDOC teams respond to
about 100 requests for help each year. The most common scenario in
Colorado is a lost male hiker or hunter.
Many victims are elderly. Marcia Koenig, a veteran handler from
Washington who now runs training seminars with Andy Rebmann, her husband,
spent last New Year’s Day searching for an 88-year-old woman who had
wandered away from a nursing home in a driving rainstorm.
Searchers had already spent 18 hours looking for the woman by the time
Koenig and her German shepherd, Coyote, were asked to help. ‘1 gave Coyote
a scent article and she found her within ten minutes,” says Koenig.
“She was less than a quarter-mile from the home, but she was lying down,
concealed in some hushes. I yelled ‘Good dog!’ to Coyote, and then ran to
the woman. Thank God, she was still alive,” sighs Koenig. “There’s nothing
better than a live Find.”
Many SARDOC teams, such as Carla Tomaszczyk of Aspen and her
standard poodle, Cassidy, take specialized search training. Cassidy is a
certified avalanche rescue dog, skilled at finding bodies—dead or alive
buried under snow At least once a week in winter, Tomaszczyk and Cassidy
head for the hills for a practice search. Today they hop on a chairlift
and ride to the top of the Snowmass ski area. At the top of the lift,
11,835 feet up, Cassidy warms her toes in the ski patrol hut while
Tomaszczyk and other handlers ear themselves out chopping up
10,000-square-foot fields of snow to resemble the chunky blocks left by an
avalanche. They then dig large, L-shaped chutes five feet deep in the
snow. A ski patroller is conscripted to drop into the chute and lie in the
coffin like tunnel at the bottom, and the chute is filled in with snow.
In this session, two ski patrol members have been buried in a
section Tomaszczyk did not dig, so neither she nor Cassidy knows where
they are. Fifteen minutes after burial, their scents have had ample time
to rise through the snow and the search begins. “Go find, Cass, go find!”
Cassidy bounds across the snowfield, her bright orange vest the only
contrast to white hair on white snow. She knows her job is to find any
human scent coming from under the surface. Within seconds, she thrusts her
nose into the snow at a point that looks no different from any other and
starts digging. ‘That’s an alert,” declares Tomaszczyk. “Where’s the other
one, Cass? Let’s go find ‘em.” Cassidy dances across the snow and almost
immediately begins digging. Right again. It seems the burial spots
couldn’t have been more obvious to her if they’d had neon arrows pointing
to them. In less than a minute, Cassidy has found both victims. It would
have taken 30 people 3() hours of delicate probing to find any victims on
a snowfield of that size, by which time they would have been long dead.
BECAUSE NOT ALL LOST PERSONS ARE FOUND alive, Tomaszczyk and
Cassidy attended a three-day course in cadaver searches. Handlers from
around the country listened to Rebmann and Koenig talk about the finer
points of finding dead bodies while 15 dogs rubbed noses and snoozed under
the meeting room tables. Showing graphic slides, they discussed the
nuances of decomposing bodies, how serial killers hide bodies and how to
train your dog to find such things. Cadaver search work is different,
Rebmann explained, because dead bodies all smell alike. No scent articles
are needed. Instead, the dogs learn to search for a characteristic cadaver
odor and a special command that means “find dead people.” Some use “Find
the baby,” others, the more palatable “Find Fred.”
The students are trained using Pseudo Corpse, an odoriferous substance
made by Sigma Chemical Company just for training search and rescue dogs.
In a hotel parking lot, Cassidy and the other dogs lined up to get a good
whiff of the chemical, then took turns finding it when it was hidden in
one of several concrete blocks. “We’re not training the dogs to find
bodies,” Rebmann explained. “We’re training the dogs to find scent.”
Cassidy obviously learned her lesson well. When visiting family in Indiana
last year, Tomaszczyk and Cassidy were called out to look lot victims of a
serial killer who, as it turned out, liked to bury bodies in his yard.
Based on her training with Pseudo Corpse, Cassidy easily pointed the way
to human remains.
Of all the search and rescue dogs now working in the United
States, only 73 have gone on to be certified as either a basic or an
advanced “disaster dog” by the Federal Emergency Management Agency (FEMA).
It’s a relatively new specialty. Some handlers say they are reluctant to
expose their pets to the dangers of searching in urban disasters, such as
the aftermath of an earthquake, although few of the dogs that worked at
the site of the Oklahoma City bombing sustained any injuries. (The
handlers did not fare as well. Of the 50 who responded to a survey, 16
have since left search and rescue work due to the emotional impact of that
event. None of the FEMA certified teams have dropped out, however.)
FEMA training is tough. Not only must the dog know basic
scenting techniques, it must also know how to move safely in a chaotic
scene full of potentially fatal hazards. At a basic FEMA test held on a
hack lot at the Ontario, California, airport, ten dogs from around the
country are attempting to earn certification. Most of them have easily
passed several parts of the test, including a long stay, a drop on
command, scent detection and verbal directional control (in which the dog
runs the bases on command from a handler who cannot venture beyond home
plate). The agility test, however, which determines if a dog is ready to
pick its way safely foot by foot through a collapsed building or train
wreck, is not so easy.
Ivey, a German shepherd belonging to Nancy Hachmeister, has
successfully completed the test’s early stages hut is balking at climbing
a ladder. She climbs a few rungs and stops, quietly whimpering.
Hachmeister talks to her in a low voice, “Come on, honey, go. You’re not
doing this very well, honey.” Ivey eventually climbs the ladder, but then
refuses to go on to the next step, insisting on going right back to the
ground. Hachmeister is not discouraged by Ivey’s failure. They’ll take the
test again.
“You die a slow death as an evaluator, watching
a dog fail,” notes an experienced handler who is judging the test. “But
really, failing is not so much failing as it is just a part of the process
toward Certification.
Sunny, a 95-pound Doberman pinscher sometimes called the
“search pony,” trembles as he climbs the ladder, guided by his 105-pound
owner, Shirley Hammond. He is a bit more confident on the seesaw, walking
up the plank, balancing just beyond the fulcrum while the upper portion
sinks to the ground, and slowly picking his way hack down. He breezes his
way through the tunnel crawl and across an unsteady pile of sheet metal
and chain—link fencing.
The final part of the exam is the rubble pile. Only five of the
dogs have done well enough to advance to this stage. Three evaluators in
full safety gear are perched on top of a 15-foot high pile of concrete and
twisted steel, and one victim has been hidden inside a concrete tube.
Shouting commands from a fixed position on the ground, each handler sends
his or her dog up to find the victim. Each team has just ten minutes.
‘While two-dozen people watch in silence, Sunny carefully picks his way,
across the rubble, slowing a bit when crossing a shaky wooden pallet.
After a few minutes of sniffing around, he stops. He lets out a bark and a
long, plaintive howl. Another bark, a longer howl. Everyone holds their
breath. Finally, Sunny lets loose with several short harks, the repetitive
noisy alert that is required fur urban disaster work. He has found his
victim. The evaluators declare him a certified FEMA dog, one of only three
animals to pass today.
When the results are announced, everyone, including
those who didn’t pass, gives the three teams a standing ovation. Then all
begin the long drive back to homes and day jobs, to practice some more and
wait to be called.
The next morning, another eight dogs gather to attempt the
even more difficult advanced FEMA test. This time, six victims have been
scattered among three large rubble piles, along with scent-laden clothing,
noisy generators and other distractions. A. J. Frank, a firefighter from
Seattle, and his 4-year-old chocolate Lab, Ohlin, approach the first site.
The scenario: a two-story senior-citizen complex has collapsed. Wearing
a bright orange jumpsuit and hard hat, Frank asks several questions about
the potential number of victims and any known chemical or electrical
hazards. He then sends Ohlin scrambling to the top of the pile, searching
for the scent of victims. “Are you a search dog?” he calls when the dog
reaches the top and looks back for guidance. “Go search!” Frank continues
shouting directions at Ohlin from the ground until they have found two
victims, and Frank figures they have covered the entire pile. At a
debriefing, Frank draws a map of the pile and the probable locations of
victims, while Ohlin wiggles his ears at flies and plays with his reward,
a deflated soccer ball.
By the end of the exam, Frank and Ohlin have found
only four of the six victims, not enough to pass. For a while Frank, who
has been laughing and joking all day, walks with his eyes downcast, his
step noticeably slower than before. But he isn’t giving up, he says,
brightening. He’ll be back.▐
