Thanks, Cutie, those plans of Praia da luz and the Ocean club are very handy.
So the car park where the dogs traced Maddies scent to was directly across the road from the Tapas bar?
Yes it appears so.
But it has never been clear to me which door the dogs and handlers exited out of 5A: Front door (which overlooks the car park) or patio doors (which overlooks the pool, TB, ocean).
You also need to read the text. Obviously some time had passed from MM's disappearance to the dogs being deployed. The wind can alter the direction of the lingering scent. Plus also remember MM was legitimately walking in the area with her family shortly before she disappeared.
The big takeaway for me is the dogs were unable to scent outside the immediate vicinity which supports MM going into a vehicle and being driven away. The dogs did not scent down to the beach, remote areas, a building etc.
