P Pavlov's theory is used in the case of the E.V.RD. system of alert. He has

been 'conditioned' to give a verbal alert when coming into contact with 'dead

body scent'. The presence of tangible material is not required to produce the

response.

Note he does not say blood.


I would expect, that if Eddie, went out on a case purely to find blood, then he would act the same way as Keela, i.e. sniff, nose down, and freeze in one spot. If both dogs used then I expect the police are looking for cadaver scent and blood. One barks one freezes.

Otherwise what would be the point. Why would you train one dog one way to find blood, and another dog the other way. That is how I would think the investigation came to the conclusion it was cadaver scent.

Doh, I know what I mean anyway

That is very interesting indeed.
He 'barks' if he finds cadaver smell. Fascinating.
Perhaps this is why Martin Grime and the police came out with the idea that they should search for signs of cadaver in the boot of the hired car.
Now another thought I have been chewing over.
I had been wondering why the dogs seem to go backwards and forwards, time after time, before settling or barking.
Initially it looks as though they are uncertain, but then I thought, the dog has some ? 2,000 olfactory nerve cells? (please can someone correct me) and can smell masses and masses of different smells, compared with us humans and our limited human cells.
Now I think I understand, if dogs have that many smells to identify and sort out, no wonder they would need to keep going back and forth, to be sure that they had really sifted out the one they are searching for.

Up to very recently we had two pointers. both sadly died in the last year. They were never trained by us to hunt but both would track from side to side hunting a scent, then the bitch would go to point and the dog would give a secondary point but at the bitch not what she had found. It came naturally to them through their breeding. But they tracked the scent through all other scents as in horse muck and fallen fruits.

I'm sorry about your losing your lovely dogs nina, they become so much part of the family, and I think it is becoming more and more evident from our discussions that dogs are amazing when it comes to their skills in detecting smells.
The police, mountain rescue, hunting dogs etc. would not even be comtemplated as being 'in service companions' if they didn't cut the mustard.
I think Gerry, after all of his bragging and swaggering, is beginning to look as if he is standing all on his own-some, lonesome little self in doubting the police dogs and what skills they can bring to an investigation.

E.g. in England, where he went shortly afterwards to get Madeleine's DNA [and saved a passenger's life on the plane out and got pick-pocketed whilst withdrawing money in London with his non-existing card]. IMO possible [pants on the master room bed] and nothing more than that.

Later I thought that Kate was ready to drop him into it [around the time of the viral video]. But, again, never been sure and still aren't. IMO the only thing is that a lot points to them knowing more than they're saying.
