[05:28.91]It might be thought that
[05:33.09]with all the advanced technology available to the police,
[05:38.39]dogs would no longer be needed.
[05:42.00]However,this is very far from the truth.
[05:46.31]There are many aspects of police work
[05:50.09]that dogs perform much more efficiently
[05:53.70]than the combined efforts of men and machines.
[05:58.40]For example,no machine yet invented can hear or scent an intruder at some distance,
[06:07.20]pursue him through water or over obstacles,corner him,
[06:12.40]and hold him safely until help arrives.
[06:16.50]A dog can do all that and much more when properly trained.
[06:22.80]Only a few breeds are suitable for police work.
[06:27.79]They must be strong to undertake the demanding physical work;
[06:33.59]they must be big and imposing 5 so as to command respect;
[06:38.68]they must be intelligent in order to absorb all the specialized training.
[06:44.38]As they are expected to work in all weathers and under all kinds of conditions,
[06:51.59]they must have a coat that is suitable.
[06:55.16]It must be one that is not so short
[06:59.84]that it offers little protection from the cold or from rough terrain,
[07:05.33]nor so long and shaggy that the dog becomes too hot,
[07:10.24]or hair so long that it becomes caught up when the animal is working.
