Dogs bring out the best in people so the only surprise about this simple but heartwarming series is why it wasn’t dreamt up before.

To get series two up and running, Caroline Quentin takes a bracing walk along the
Helford estuary.

Meanwhile, Dom Joly is on Hadrian’s Wall with his two black labradors, and former Wales and Lions rugby captain Gareth Thomas is in the Brecon Beacons for a steep climb or two with his German pointer, Boyo.
