STUBBORN Portuguese police chiefs are refusing to let the world's best sniffer dogs join the hunt for Madeleine McCann.
Senior British cops last night urged officers leading the inquiry to accept help from UK dog teams before it is too late.
Two dogs attached to Britain's National Policing Improvement Agency have developed such powerful tracking skills they can follow a scent for miles — even one up to 28 days old.
By sniffing an item of Maddie's clothing, they could trace a trail that might finally unlock the mystery of the four-year-old's disappearance.
Police in the Algarve appear no nearer to finding Maddie 20 days after she was snatched from her bed in the family's holiday apartment in Praia da Luz. But the sniffer dogs are still being snubbed.
A senior UK police source said: "It is an absolute scandal — time is fast running out for this little girl
These dogs can only sniff out clues within a 28 day period.
We have a few days left! We must help to get these dogs in NOW!
