Whilst yomping the dogs to Looe the other day we met another black Labrador out with his owner. The Lab’s owner nodded at Herc, who had his customary rock clamped firmly in his mouth.

“My dog picks-up plastic bottles from the beach.” The man said grinning.

“That’s very environmentally friendly of him!” I retorted “I’m afraid Herc is doing his bit for coastal erosion!”
