Police Dog Training?

[dreamer14_14]

I want to write a story about a police dog and I want it to be realistic, but I don't really know that much about police dog training. The story will follow a German Shepherd puppy from the time it's a puppy to when it's a police dog or soon after that. I have a few questions about the training.

1) Are there ever any mutts or mixed breeds that go through police dog training and become a police dog?
2) What are the stages and details of training that a police dog will go through?

Answers will be much apprectiated. <3

As far as I know,there can be police dogs which are not pure bread(they can be mixed)...as for the training,it has to start at a very early age so that he masters the skills of basic training while still young and move on...i googled this for u and discovered that in canada they only use pure bread german shepherds: http://www.rcmp-grc.gc.ca/pds/dog/selcdog_e.htm
