Maddie hunt: Send in dogs The Sun
By Ian Hepburn and John Askill
Published: 23 May 2007 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 have immense capability. Their tracking skills are among the finest in the world.
"The dogs were put on standby to go to the Algarve within days of Madeleine’s disappearance.
"You would expect the Portuguese to make use of the best resources available to them, but they repeatedly ignore the offers of assistance."
The dogs include a spaniel whose sense of smell is so keen she can sniff traces of blood on a weapon even after it has been scrubbed clean.
But the source warned: "They work most effectively within a 28-day time frame. After that the scent becomes much weaker."
Other British dog-handling teams did join the initial search for Maddie, and local cops later reported that dogs found a scent, but the trail was lost after 250 yards.
