Dogs fierce competitor in sniffing: RATS

Not you ATS addict not the RATS forum, these ones are the real deal.

Rats have an exquisitely sensitive sense of smell and can crawl just about anywhere. This combination makes them ideal candidates for sniffing out buried survivors. For that, the animals need to be taught to home in on people, and they must also signal their position to rescuers on the surface.

What will dogs do now?

The researchers trained the rats to search for human odour by stimulating the reward centre when it found its target smell. Once the rats were trained, they were set to forage for the target smell, while electrodes recorded their neural activity patterns.
