Faithlilly contended that the Met believe the dog evidence held considerable weight (though actually doesn't provide any evidence of this). The fact that the Met have made several statements clearly indicating they believe Madeleine may have left the apartment alive and may even yet BE alive shows that whatever weight they have placed on the alerts it is not a particularly weighty weight.
To be fair to the initial PJ team, they had no prior experience of the use of such dogs, therefore they may have been reliant on whatever they were told, as opposed to the UK police who have post-mortems on investigations to determine what went well, what screwed up and why with a view to improving future practice.
The GNR did ask around if anyone had heard of someone who'd died in the flat, so they were aware of that possibility, but I've found no indication that it went beyond that to enquiring about what may or may not have been second-hand furniture, for example.
Neither have I found any indication (prior to a later question by the Rebelo team concerning blood and the expression of some bewilderment over the CC episode) that they'd asked for specifics as to what exactly was within Eddie's "training parameters" so as to exclude other potential explanations.
