Experts have said that Nicola Bulley's dog would not have been sure what to do after her owner went missing, and stayed near a "familiar smell". Willow was reportedly found running back and forth near the bench where the missing mum-of-two's mobile phone was found still connected to a work call.
The 45-year-old has now been missing for two weeks and friends have been out appealing for anyone with any information to come forward.
Animal behaviour and training consultant Nina Bondarenko told the Daily Star Willow displayed "flushing behaviour" after being found without her owner.
