I have trawled your posts and found this;
http://csst.org/forensic_evidence_canines.html
The descriptions of the different dogs don't seem to compare with anyone else's descriptions, that's the problem here. Using their criteria and Grime's description of his training Eddie was not one of these;
Cadaver Dog
A narrow term, used in a search-and-rescue context, to indicate a canine primarily trained as a tracking or air-scent dog that has also received cross training in the location of dead human bodies
He was one of these;
Forensic Search Dog (The primary focus of this paper)
A canine that has been specifically trained to indicate a scent source as being from decomposed human tissue. Such animals are also trained to exclude (deconditioned to) the scent of human urine, feces, and semen and will not alert on residual scent from a live human; and have never been trained to locate any scent other than that of decomposed human tissue.
Hopefully I have found the document you have been referring to, and have explained why I dismissed their description of a 'cavader dog' as not referring to Eddie.
Thank you Gunit
Eddie was basically a Forensic search Dog .... BUT !!

... BUT, looking at the part in blue
Eddie had already been trained to alert on residual scent from a live human, which includes the scent of human urine, feces, and semen Once trained, the training cannot be detrained. So he is always likely to alert to the scents of a living human human
So seems that makes him ineffective, because when he alerts there is no way of knowing whether it is to odour from Madeleines dead body OR residual odour from her living body ... or even blood from a living persion .... or the scent from a dead pig / pork [He was trained using dead pig rather than dead human parts]
The final part in red:
States that he MUST NEVER have been trained to locate any scent other than that of decomposed human tissue. .... but he has !Therefore poor Eddie whilst having a brilliant nose was unable to "definitely say" whether he was alerting to the scents from a dead body, a living Madeleine, dried blood, or pork.
Forensic Evidence was necessary .... and there was none
The long and short of it is that we just dont know what he alerted to.
You cant hang, draw and quarter the Mccanns on such unsubstantiated alerts, can you?
And there is nothing else of any substance at all against them
Gunit, I am not very good at explaining things. Hope you understand
And a big thank you to Anna for her input.
