I'm aware that some described being given a towel, but others refer to the blanket. The legal summary calls it a "blanket/towel".
At 08.00 the GNR Search and Rescue sniffer dog team came into action, searches were begun from the resort in the direction of the beach, covering a 2 km area; in Praia da Luz 300m radius searches were made as well searches of abandoned houses, wells and waste land, the radius subsequently being expanded to 600m including the verges of the EN 125 motorway.
Subsequently an attempt was made to reconstruct the route taken by Madeleine by giving the dogs
a blanket/towel used by her, but the results were not significant, given that the dogs are more trained for use in rural areas rather than urban or populated areas, the existence of more odours in the air making it impossible for the tracker dog to identify/locate the “target smell”.

Witness Statement
Date: 2007-05-16
Carlos Manuel Carvalho Lacão
Occupation: GNR Officer
He has been a GNR officer since 1988. He holds the post of soldier and currently works in the Portimao Territorial Group, working within the forensics service.
On 4th May he was called at about 01.15 when he was asleep at home, requesting him to appear at the Lagos GNR post as a small girl had disappeared. After arriving at the GNR post with his colleagues Morais and two dogs (Numi and Kit), German Shepherd dogs, which made up the search team, they immediately left for P da L. They arrived at about 02.30.
When they arrived at the scene, they entered the McCann's apartment by the front door, and entered the living room, where there were some PJ officers as well as the MCCann couple.
The just talked to some colleagues from the PJ and asked for a piece of clothing that Madeleine had worn or used recently. They were given a pink/orange blanket that the child had been covered with in her bed.They began searching with the dogs from the main entrance to the apartment,
having given the blanket to his dog Numi to smell and begin to search.
http://www.mccannpjfiles.co.uk/PJ/CARLOS-LACAO.htmAt about 23.00 the extra teams that had been requested for reinforcement arrived (Officer Rosa with Oscar and Officer Martins with Fusco, both from the search and rescue unit and Officer Fernandes with Rex and Zarus from the tracking team).
After the officers had been updated about facts relating to the disappearance, they tried to reconstruct the route the girl might have taken with the two tracker dogs.
For this purpose the dogs were given a blanket to sniff, provided by the parents, which had been used by Madeleine.http://www.mccannpjfiles.co.uk/PJ/GNR_SNIFFER.htm
