It’s now completely official. Dogs CAN do anything. I just don’t want to know how they train them.

Police in southern Sweden have a new tool in the fight against sex crimes — a sperm-sniffing dog.

A 23-year-old man was arrested on rape charges after the dog, Rapports Opus, was brought to a park in the town of Karlskrona, Sweden where a woman was sexually assaulted.

The dog found traces of semen at the scene of the crime which were found to match the man’s DNA.

Rapports Opus underwent a year of training to become the region’s only sperm-sniffing dog.

He graduated from training in August 2010 and this will be the first time evidence from his abilities will be used in court.
