I have a deep skepticism about sniffer dogs. This article by the National Narcotic Detector Dog Association just about sums it up:

>While the scientific community highly endorses double-blind testing, it can have disastrous effects on canine teams. As there is no way to determine whether the canine responded correctly at the time of the alert, the question is, should the handler reward the canine? This is a vital question due to the fact that detection canines are largely trained on a fixed ratio reward system where the canine is rewarded immediately for almost every correct response.
- azinman2 6y agoIt’s easy to go beyond fixed reward to variable, which is also very powerful.
- kzrdude 6y agoWhy can't a third party immediately confirm (or deny) the dog's alert in the double blind test?
- cptskippy 6y agoThat's what I was wondering. The whole argument that double blind testing can't work because the dog needs positive reinforcement seems specious. I'm imagining a room full of opaque cake domes with drugs under some. The dog identifies one, it is lifted to reveal the truth. No one knows how many domes hide drugs, the test proceeds until the dog/handler conclude it.
