Several breeds are used yet the German shepherd is the one chosen for police work. They have the size, strength, agility and intelligence needed to benefit the officer and the community it helps to patrol. Most people wonder why dogs are used as such an integral part of crime prevention. First, dogs sense of smell is 40 times greater than humans. Their hearing is 20 times better.
Some dogs can sniff a case of dynamite buried two feet under ground.
They have a nose for trouble. Training a dog over a human is also cost efficient. He doesn't want to drive and he never falls asleep on the job as some partners might. When your're working late at night and searching for an offender who may be armed there is noghting more omforting to know that he will probably sense the perpetrators presence before I do and alert me. The European dogs are more often chosen by the police because of their stringent breeding practices and the hip X-rays they do.
