I guess that raises the question "Was / were the dog/s used well-trained?" To be fair, I'm not sure that a study of three dogs in Hamburg really tells us anything conclusive about the accuracy of any other dog anywhere else.

This is a good explanation of the use of dogs, backed up by information from the officers who use them.
A cadaver dog indicating a scent does not mean there is or has been a dead body in the area. Of course, using them to find bodies where buildings have collapsed and there is a good chance there are dead bodies there, they will be seen as reliable. But they do and have give misleading indications. The fact is, if they were accurate to within an acceptable level, their findings would be accepted as evidence in court. And it isn't.
The scent isn't from a dead body, it is from decomposing flesh. This can be present in a cut or a wound. And can be many years old, or passed on to clothing where it remains. In the Shannon Matthews case it appears that second hand furniture carried the odour. If McCann was present in certifying the death of a patient, wearing a certain item of clothing, that scent would still remain. And could be passed on to other items of clothing. I understand there is some disbelief that McCann would take "cuddle cat" to work. Many a day I've sat with one of Abby's cuddly toys on my desk at work or in my bag as she has handed it to be as I drop her off.
I'm also amazed anyone is surprised that lots of evidence of blood was found in an apartment, rented on a weekly basis to families on holiday. Seriously? If you think that's unusual, then take a job cleaning holiday apartments. You'd be amazed the state these places get in to. Traces of madeleine's blood can be there for all sorts of innocent reasons.
I'm no fan of the McCanns' but I do get irritated with misinformation being peddled as fact.
Am I right in thinking though that the dogs were walked through the entire hotel complex and the only place they signalled was in the McAnns apartment?
I would have thought they would have wanted the dogs to search the whole place for any scents that could lead them to Maddy? Or do you think the handlers were being biased somehow, unconsciously perhaps? I suppose you would expect the blood dog at least to signal elsewhere.
So do you reckon the dogs would have signalled in most of the other rooms in the complex had they been told to search? Do they just give the police an idea of where to look for dna? I'm failing to see the point in them now...
Definitely useful where there are actually bodies. In that situation there is a strong scent as the decomposition is actually still there. Where they are known to give "false positives" is where the source of the scent is no longer present. In that respect they are simply indicating that a scent is present, what or whom that scent belongs to is something they can't detect.They are very good at finding buried bodies. My father works with them, has for the past 10 years and they've never given a "false positive" when searching for buried bodies in fire scenes.
He doesn't work in just house fires where its a small, contained space... he's worked with them in huge factories that have caught fire or entire complexes.
How long does the body need to be decomposing for it to release a scent strong enough to be detected by the dogs? I just find the hit in the apartment hard to believe, as the time between when she was last seen and when the alarm was raised seems to be fairly short for a body to begin legitimate decomposition? I could be wrong though...
