Police have requested the help of a dog whisperer and behavioural profiler in the search for missing mum-of-two Nicola Bulley, it is reported.
The 45-year-old was last seen over three weeks ago, at 9.10am on January 27, while walking her springer spaniel Willow in St Michael's on Wyre, Lancashire.
Her phone, still connected to a work call for her job as a mortgage adviser, was found just over 20 minutes later on a bench overlooking the riverbank, with her dog wandering loose while "bone dry" and "agitated".
