Eddie could have been alerting to any body fluid, or it could have just been a false alert.
Either way there was no body................So if anyone believes there was a body, Where is it?
The McCanns were not familiar with the area.
No evidence of anything really.

“The initial training of the dog was conducted using human blood and stillborn decomposing piglets. The importance of this is that the dog is introduced to the scent of a decomposing body…He has additionally trained exclusively using human remains in the U.S.A. in association with the F.B.I. The enhanced training of the dog has also involved the use of collection of ‘cadaver scent’ odor from human corpses using remote technical equipment which does not contact the subject.”
http://www.theolivepress.es/spain-news/2012/08/09/missing-link-overlooked-in-the-madeleine-mccann-case/‘Eddie’ The Enhanced Victim Recovery Dog (E.V.R.D.) will search for and locate human remains and body fluids including blood in any environment or terrain.
We know that Eddie has been trained using blood, bone tissue, teeth and decomposed cross-contaminants… so it is feasible to say that he could alert to skin tissue or other decomposing bodily fluids from a dead or living human being. We also know from the Haut de la Garenne case that Eddie did alert to tissues used to clean up after sex..
