A search and rescue dog which helped locate survivors of the Clutha disaster is up for a national award at Crufts.

Border collie Taz, the senior search dog at Trossachs Search and Rescue, has been involved in many high-profile operations over his nine-year career.

His successes have led to him being nominated for the Friends for Life trophy at the Crufts dog show in Birmingham this weekend.

His handler Gayle Wilde showed STV how he would carry out a search underneath a church.

On November 2013, Taz and his team were called to the Clutha in Glasgow, after the police helicopter crashed through the pub roof.

They worked in cramped, dark and dangerous conditions to locate the survivors and relay their locations to the fire service, who were able to extract them.

Over the years Taz and Ms Wilde, 39, have been involved in numerous searches or missing people and in collapsed buildings.

More recently, Taz was involved in the search for the missing fisherman Paul Alliston in the Outer Hebrides in 2016.

The pair are on call 365 days a year and receive no pay or government funding for their work.
