SNIFFER dogs used to search for Madeleine McCann were not properly trained.
Police used dogs more suited to rural work to search a 10-mile radius of the Ocean Club complex in Praia da Luz where Maddie was snatched on May 3 last year.
The dogs lost her trail in the nearby car park.
It is the latest damning revelation to emerge after the release of files from the bungled Portuguese police investigation.
Prosecutors Joao Melchior Gomes and Jose de Magalhaes e Menezes slated the probe, noting detectives had "achieved very little in terms of conclusive results".
The report also damned the Portuguese police for failing even to establish if the five-year-old is alive or dead.
