Clare Balding continues to ask the great British public to help track down a selection of missing dogs, which have been separated from their heartbroken families for weeks, months, and, in some cases, years.

Anyone watching the programme who has any information as to the whereabouts of these lost dogs, will be urged to contact the programme anonymously, and any useful leads they offer will be passed on to a nationwide network of volunteers who specialise in reuniting missing dogs with their owners.

Clare also showcases several stray dogs who have been handed into rescue centres across the UK, and whose owners cannot be located.

Also in this week's programme roving reporter Radzi Chinyanganya finds out about the incredible search and rescue of terrier Millie with the help of a specialist drone team. Vet Mark Abraham talks us through the facts and myths about microchipping our dogs. JB Gill heads to Cornwall to train with sniffer dogs who are experts in tracking other dogs that are lost.

And we hear about the extraordinary rescue of beloved family pet Suka who disappeared down a disused tin mine.
