A woman raised the alarm over Nicola Bulley's disappearance after finding her "worried" dog alone next to a deep river.
The business owner, who did not want be named, spotted Nicola's brown springer spaniel Willow running free on the river bank on Friday morning.
She also found Nicola's mobile phone on a bench by the side of the river, under a tree which has a sign warning of deep water nailed to it.
