Tell me something Icabodcrane. How does a handler know if a dog has missed a target?
The statistics are bunkum basically.
Lets put this fantasy science into perspective. Those that promote the dogs and earn a bundle out of them speak of figures exceeding 80% accuracy but the thing is they don't know when a dog has missed a trace because it isn't registered. Consequently the rate could be very much lower than that claimed.
And to think the Portuguese thought they were infallible? Crayzee stuff

So you base your conclusion on what is not known, rather than what is
That is how fantasy is defined, John
Mr Grime, in a pretrial, testified how and where in September 2007 Eddie had alerted in the US Parker case (a woman was missing for a year when her husband was arrested for murder). No body however had been found.
Mr Grime was mocked, it shouldn't be surprising for some posters, by the defence attorney who suggested Eddie smelt food instead of remains. Mr Grime replied this
I can’t predict the dog’s behavior. I study the dog’s behavior. You are trying to put words in my mouth and I don’t deal in hypotheticals.The judge finally decided to reject the cadaver dogs alerts (another dog had alerted, months before Eddie). It was a deception for the FBI which considered this case as a "test case" where cadaver dogs would help in the prosecution of a no body murder trial.
Nevertheless the jurors agreed with police and prosecutors and convicted of murder the husband, an ex-police officer, in September 2009. He was sentenced to life.
One year later his wife's body was found.
