They did find Madeleine's scent. It is proven from statements and facts.
If they were following Madeleine's scent it was hugely significant.
If the scent came to an abrupt halt with both dogs losing it in a car park ... that is hugely significant.
It would appear that Madeleine had been taken from the apartment and taken by a circuitous route to a waiting vehicle.
Yet the significance of that would appear to have escaped the investigators who were already formulating suspicions about the involvement of Madeleine's parents in her disappearance ... the request to see a priest being one of the triggers for this.
No-one appears to have been asked about parked vehicles at that spot ... vehicles are only mentioned in passing by Mr Carpenter and the cook who appears to have had more concern about them than the police to whom he gave his statement.
Perhaps a perfect example of some of the search for evidence to solve a crime is ignored when the search for evidence to fit a theory is given paramount importance.
Why look for a live child when your theory dictates she is dead.
Why look for an outsider when your theory dictates it is an inside job.
Why look for a vehicle when your prime suspects have no access to one.
So if you are correct and the dogs did indeed follow Madeleine McCann's scent to the car park ... someone at the head of the investigation has an almighty sin to answer.

These vital clues were never followed up by the Portuguese police, according to Isabel Duarte, the Lisbon lawyer acting for Madeleine’s parents, Kate and Gerry McCann.
Shortly after Madeleine was taken from Apartment 5A at the Ocean Club at Praia da Luz, five years ago this Thursday, a sniffer dog picked up her scent at a nearby car park.
Mrs Duarte said: “This was a significant moment at a critical time, yet there is very little about it in the police files. There doesn’t appear to have been any forensic work at the spot in the car park identified by the dog. More work should have been done.”
