- [Voiceover] Someday,
this little guy could be
  a bomb-sniffing dog
  with a SWAT team.
  In fact, Thunder has
  now been training
for almost three months.
  He's in PennVet's
  Working Dog Center,
 class of 2013,
   the center's first class.
  Along with seven classmates,
  he trains each day.
 They are all specially
 selected dogs,
 groomed from a very young age,
 to work with police, military,
or rescue search teams.
   - Whether it's search and
   rescue or cadaver work,
the bombs, or narcotics,
we'll be able to imprint
them with the scent, or
whoever buys them will
be able to imprint them
with the scent.
   - [Voiceover] The puppies
   go through intense
physical training, and
learn important skills.
  They need to be able
  to work effectively
 in difficult, and, sometimes,
 dangerous situations.
At first, the tasks are simple,
  like learning how to
  climb and balance,
   but their work quickly
   becomes more challenging.
   In this exercise, Kai
   searches for a hidden tug,
a piece of leather with
a recognizable scent.
 Local police help the
 Working Dog Center
 by imprinting towels
 with different scents,
such as cocaine, or explosives.
  The dogs can then
  learn these scents.
  Police do use the real thing
  when imprinting a scent.
 The tug is hidden in the
 floor, under the drain cover.
  Kai will indicate
  that she's found it
   by scratching at the area.
- After they leave here,
they'll probably attend
   a normal narcotics
   school will be
 between ten and twelve weeks.
   Explosives can go anywhere
   from ten to sixteen weeks.
There's a lot of
different scents
  that they have to be taught.
- [Voiceover] This time,
Kai must find a person
   who is hidden in a barrel
   at this construction site.
  Kai is trained to ignore
  these people standing here.
In a rescue situation,
she cannot be distracted
   by rescue workers.
 Here, Socks is looking
 for the leather tug
  in a warehouse room.
She will sit to indicate
that she's found it.
 The sit indicator is important
  for searches for explosives.
  Search dogs must not
  scratch at bombs,
  for obvious reasons.
   These dogs train
   five days a week.
Foster parents take
the dogs home at night,
then return them each
morning for more school.
  The dogs train here
  for about a year.
