Why did the sniffer dogs fail to find Madeleine?

[Jazzy]

Please remind me why the Mccanns are free and charged with nothing?

[Jazzy]

What is new to discuss? Where is the new evidence , not already dismissed by the Portugese Attorney General?

[AnneGuedes]

Please remind me why the Mccanns are free and charged with nothing?

They are presumed innocent, it doesn't mean they are 50% or 70% innocent, they are 100% innocent up to further notice.
Once this is clear in all minds, we can debate and try to understand what happened without having posters claiming they weren't charged, sceptics are insane, etc.

Irrelevant post as the subject of this thread and the subject of my previous question was about why the dogs found no trail in certain quarteras  its ok i understand u have no idea why but no reason to derail

[sadie]

Cool by me


But before you go do remind us why the dogs never found madeleines scent in any direction of both bundleman and smithman

I can tell you why.

It was only air scent, and a very little girl held high on a very gusty night. 

The dogs came hours later, no scent remaining.

Correct Sadie.  The scent dogs would only have been able to follow her trail had she put a foot on the ground.

The fact that they were able to follow a trail out of reception, across the road to the lamp post just goes to show that they were following her scent.  Unfortunately it was a trail laid down innocently as she walked to the kiddie club.

So if Madeleine  had woke and wondered, the dogs could have tracked her  ? 

That's one theory we can lay to rest then

No of course you can't, if a prisoner escapes & dogs are sent out to trace his scent but cannot find it, does that mean that the prisoner did not escape? It just means that the dogs failed to trace the scent or the scent may have been too weak. You can't rule out anything on account of DOGS, because there is no such thing as an infallible dog.

The "innocent" trail out of reception across the road to the lamp post John is mentioning does not start at the OC reception.
It is imperative, when someone is missing, to bring the sniffer dog at the exact point where the missing person was last seen. No sniffer dog was brought to the OC reception because Madeleine was last seen in the 5A. The 3 dogs brought to the 5A followed the same route and that route was by no way the route Madeleine followed to go the creche.

You are quite wrong Anne, John was responding to my post,

So it did start at OC flat 5A

Have you a link ?

Yes, I do - (though I'm waiting for you to provide a link to the dogs in PDL having received  cadaver AVOIDANCE training, but never mind, eh.)

The snifers dogs of the GNR national school (an army department) are trained like other police snifers dogs, they participate in international sessions, there's nothing specific with them.
Here is an interesting article about air scent dogs, trained to detect generic alive human scent and only that. After the rescue operations, these dogs are taken back home and only then other teams come and deploy sniffer dogs trained to detect human cadaver scent and only that.
These dogs are trained during 18 to 30 months (together with the dog handler) and pass then through a very complex selection process. The training has nothing to do with what people can obtain from their pets. The dog must be capable to concentrate and ignore any other scent, how tempting it can be (part of training of males is "resisting" to oestrus female). Their hearing qualities (more accurate than ours) are developed as well.
For obvious reasons alerting to cadaver scent would mean radical rejection for a candidate to authentic air scent dog.
The article is in French, does it matter ?

Once a find is confirmed, the dogs are removed so that the victim can safely be taken out. Because searching is essentially a game, a find is always rewarded – usually with a toy – to ensure the dogs remain motivated.

Zörner said a dog worked for 20 minutes, because "If it works too long the dog loses interest and the work is no longer secure – he can give an indication even when it is not absolutely sure," and then rested for the same amount of time.
