It is relevant insofar as the Portuguese don't have the same resources to call upon as the UK when a child goes missing. It is such a rare event there, after all, so rare that the co-ordinator of the investigation had only dealt with 2 previous cases. Or maybe they just didn't know the correct type of dog to request attend from the specialist team.
I don't know how many times I have to post the evidence, but here goes again. They knew exactly which dogs they needed;
At 01.00 [on 4th] after the group commander had been briefed about the situation, telephone contact was made with an official from the Queluz GNR school, with the aim of their releasing search and rescue dog teams, seeing as these are specially trained to find missing persons, which is not the case with the Portimao sniffer dogs, which are essentially patrol dogs.
These dogs came.
Sargeant Silva - Dog: Timmy
Officer Cortez - Dog: Sacha
Officer Sousa - Dog: Kolly/Cookie
Officer Rosa - Dog: Oscar
Officer Martins - Dog: Fusco
Officer Fernandes - Dog: Rex/ ZarusAt 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).
