When Mr and Mrs Dartmoor win a new motorhome in a competition, it gives them the opportunity to travel to the Algarve region of Portugal for a road trip holiday with their now grown-up (yet continually mischievous) border terrier Mabel.

This is the question Mr and Mrs Dartmoor ask themselves as they take a leap of faith and embark on a further adventure with their little dog.
