If memory serves me well, the GNR dogs followed a trail from the door of the apartment and along the walled pathway in the direction of block 4. They walked down the pathway between the blocks and followed the path running behind block 5 where they exited onto Rua Dr Francisco Gentil Martins prior to proceeding back up the road in the direction of Rua Dr Agostinho da Silva and crossing before turning and walking back towards the car park opposite reception. (we went into this in great detail with Pegasus on one of the interminable dog threads ... Misty might remember).
They showed not the slightest interest in the exit from the garden of the McCann apartment.
I doubt Madeleine would have followed that route by herself in the dark and on foot. If the dogs were following her scent she was being carried by an adult who was walking to a vehicle in the car park.

Witness statement of GNR Dog Handler Antonio Freitas Silva...
That after having given the sniffer dog the towel and next to the residence of the missing girl, more specifically, next to apartment block 5A and 5, the first sniffer dog headed toward the door of that apartment. Immediately afterward, he headed in the direction of block 4, returned around block 5, and came down a road that exists between this block and the leisure area (pools, restaurants, etc). He turned right; in the direction of the aforementioned apartment and headed toward the main road. There, he crossed the street and next to the wall of block 6, turned right, and headed toward the contiguous parking area. More concretely, he headed next to a light post and sniffed the ground around that post. After this, he crossed the street again and headed toward the access zone to the restaurants and pool area, sniffing the door which was closed at that time. He again went to the parking zone, and at that point, lost the scent.
- When carrying out this operation with the second dog, he followed the same route, took the same direction and headed toward the light post in the parking lot mentioned above. He sniffed the area and at that point appeared to have lost the scent. The only difference was that this dog did not head toward the entrance of the restaurant or the pool area.
