Ok, I summarised what we discovered here tonight re GNR dogs route
The dogs route photo from the Daily Mail.
Portuguese GNR dogs searches 4th and 8th May 2007
The GNR dogs are tracking (trailing) dogs that would follow the scent of a person on the ground and not if the person is been carried. They need to start 'working' at the last place the person was seen.
Only couple of hours after Madeleine went missing, on May 4th 2007 two dogs were employed, the two dogs separatelly showed a route around the holiday complex and both stopped at a car park next to OC.
They were given Madeleines piece of clothing and they followed Madeleine's scent and they lost it at a car park.
The operation was repeated on the May 8 with different 2 dogs and these dogs also went the same route, around the building and to a car park.
These dogs show the freshest route Madeleine went by walking, all of the dogs after given to sniff of Madeleine's clothes went outside of the apartment 5A, through the main doors.
They all followed the same route, in between buildings, and around the complex to the car park.
This would indicate that Madeleine's freshest route, according to the tracking dogs was around the block and to a car park. This would also mean that Madeleine was not being carried, she was either walking there, or was walking holding someone's hand.
The third solution, which needs to be investigated, would be Madeleine possibly being put to a push chair where her feet were touching the ground.
The parking area next to the OC was never investigated, in terms who usually parks there and who parked there on the night Madeleine went missing.
What is known is that OC staff often parks their cars in this parking area.
Note: Madeleine could not walk off and wander herself due to the apartment window and shutter being open, which Madeleine could not perform by herself.
NOTE: All 4 of the dogs went through the main (front) doors which were locked when Madeleine went missing
