It will have been puzzling to anyone, tryng to piece together all the evidence gathered. And, as far as I know, all he has insisted on was a belief that there was no abductor. The rest was hypothesising., ie the how, when and where of the child's demise. Remember, the Portuguese police had not even heard of cadaver dogs, let alone use them, before this case. (source was a PJ spokesman, whose name escapes me-the one who had said they are not suspects and days later said they were)
There is really no excuse for not making oneself familiar with with workplace instruments, particularly if they are to be used as an integral part of one's job.
The Rebelo investigation probably put the correct interpretation on the expert advice given by the handler ...
" Every alert can be subject to interpretation, it has to be confirmed.
The signals of an alert are only just that.
Once the alert has been given by the dog, it is up to the investigator/forensic scientist to locate, identify and scientifically provide the evidence of DNA, etc." MARTIN GRIME: ROGATORY STATEMENT:03-CARTAS ROGATORIA 5 Pages 21 to 25
That certainly was clear enough at the time; unfortunately Mr Amaral just didn't understand it at the time or perhaps it wasn't explained to him as succinctly as it was laid out in the rog.
The Rebelo investigation didn't just run with the advertising blurb ... they wanted to know how the mechanism actually worked ... it seems they were able to accomplish that which led in due course to the release of the Drs McCann from their arguido status and unfortunately the shelving of the investigation into Madeleine's case.

PJ admits innocence of the McCann coupleThey also doubt that the dogs that were used by the British police could have detected cadaver odour.
If the child did, in fact, die in the bedroom, was the short period that she stayed there, enough for odours to be released?
What biological transformations occur during the first hour after death?
These are the questions that they are looking for answers to.
