Police dogs

Police officers use dogs for certain things.

There are a few different types of dogs that are used, usually they are Dalmations and German Shepards. And sometimes there are Labs, like Black Labs.

German shepards are used to protect the officer and CAN attack.
Black labs are usually used to sniff out dogs and drugs.

The only way that police dogs can stop being a "police dog" is if they become pregnant and have to raise puppies. Other than that, they always stay a police dog. I think that they should have time off because if they get tired, they wont work their hardest.

How do they train drug dogs?
Well, usually, they use a white towel, they make sure that there is no scent of anything on it. And then they roll up a bag of marijuana in it. After playing with the towel for a while, the dog will get used to the scent.

Also, they use the same technique for bombs/explosives.
