Tiny Chiuaua Set to join Japanese police force.
When I first read the article title, I was like "huh really?", because when I think police dog, I think of a dog that can attack if needed. But it makes much more sense that the dog is going to be a search and rescue dog.

Momo competed against golden retrievers and German shepherds to win a place as a contract police dog
A chihuahua named Momo (Peach) has passed the exam to become a dog in the police force in western Japan, in what seems to be a first.
The 3kg (6.6lb) dog is set to become part of a search-and-rescue team used for disasters such as earthquakes.
Its small size means it will be able to squeeze into places too narrow for dogs such as German Shepherds.
Chihuahuas, named after a Mexican state, are one of the the smallest breeds of dog.
"It's quite rare for us to have a chihuahua work as a police dog," said a police spokeswoman in Nara, western Japan.
"We would like it to work hard by taking advantage of its small size."
Momo, aged seven, will begin work in January.
