Beat the Bloodhound, Part 2

A revisit of the “Fool the Bloodhound” myth from 2007. Adam and Jamie
investigated new suggestions for evading detection by a scent hound, using
the same dog (Morgan) and handler from that earlier episode. Given a
five-minute head start, Jamie fled while using…
Myth statement Status Notes

…a literal red herring. "Busted"
Jamie spread canned herring across his path in attempt to throw Morgan off
the scent. The dog stopped to eat the fish and passed the point where Jamie
turned off the main trail, but later doubled back and found him.

…a suit treated with cleaning products intended to neutralize
odors. "Busted"
Despite Jamie’s suit and choice of hiding places to shelter himself from the
breeze, Morgan found him without difficulty.

…an escape route that crosses a river (rather than a small stream as in
2007). "Busted"
Morgan was able to pick up Jamie’s scent in the water and find him. Adam and
Jamie concluded that the size of the body of water had no effect on a
bloodhound’s ability to track fugitives.

…a complete full-body cleaning and equipment to mask his scent. "Busted"
Jamie scrubbed himself down and rinsed with wipes meant for use by hunters to
disguise their scent, then put on a protective suit with a gas mask and air
filter to remove odors from his breath. He sprayed a false scent trail using
his own wash water, threw the sprayer into the tall grass, and hid. The trail
distracted Morgan for a short time, but he soon found the sprayer and tracked
Jamie to his hiding place.

Adam and Jamie also explored a bloodhound’s ability to single out a suspect
from a group.
Myth statement Status Notes

If several suspects flee at once, the dog can find a particular one after
being given his/her scent. "Plausible"
Five men each provided one unwashed shirt, then fled together for a short
distance before splitting up. Morgan was given one of the five shirts for a
scent, then began to track; he initially had the correct trail, but soon
became confused and could not find it again. In a second test, he did find
the correct suspect, leading Adam and Jamie to conclude that picking a single
suspect out of a lineup in this manner was a plausible but unreliable method.
However, it was noted that Morgan was not trained to track multiple targets.


Beat the Sniffer Dog

Four contraband-detecting dogs – Buck, Rex, Gypsy, Max – and their handlers
took part in a series of tests arranged by the Build Team. They investigated
the possibility of fooling the dogs by…

…masking the scent of the contraband with a much stronger one. "Busted"
The contraband was packed into a plastic container with one of five strong
scent materials (coffee, peanut butter, citronella, perfume, and bleach) and
hidden in a large warehouse filled with props. Rex was able to find the
package every time, with only the citronella slowing him down to any degree.

…using an ultrasonic dog repellent device. "Busted"
Kari tested out such a device on her own two puppies to verify its
effectiveness. The Build Team then set up a typical outdoor-concert scenario,
with over 200 people gathered in a parking lot and possible distractions for
the dog: a car with stereo blaring and a fast food truck. One person was
given the contraband and the repellent device to trigger whenever Gypsy came
too close, but she was able to ignore it and find her target.

…distracting the dog with another scent. "Busted"
The concert scenario was reset and a female dog in heat was placed near the
person with the contraband, in an attempt to distract the male sniffing dog
with pheromones. Max did become confused, whereupon his handler removed both
him and the female from the area; after a few minutes, Max was brought back
in and successfully found the contraband. The handler noted that it is
standard procedure to remove all other dogs from the area being searched to
prevent this sort of situation.

…packing the contraband with materials intended to cause a false positive
and/or repel the handler. "Busted"
Tory fitted a false bottom into a suitcase, loaded the contraband into this,
then packed that suitcase and several others with the chosen material. The
cases were hidden in a large warehouse full of luggage. Tests with strongly
aromatic cheese and sausage, and with dirty diapers from Kari’s baby, failed
to deter Buck from picking the correct bag or his handler from searching it
to find the contraband. The handler noted that both dogs and their handlers
are thoroughly trained in seeing through attempts to deceive them.
