A dog called Clyde chased a group of seagulls so far out to sea that a lifeboat was called to bring him back.
The six-year-old Italian Spinone hound had managed to swim 500m from the beach at Happisburgh when owner Louise Brooks called the coastguard.
Happisburgh RNLI lifeboat station volunteers sprang into action, launching their D-Class lifeboat Spirit of Berkhamsted at 4.24pm on Sunday.
Cubitt Siely was at the helm with Tony Phenix and Sean Ferguson as crew, and within minutes they spotted the dog swimming 500m off the beach.
Mr Ferguson got into the sea to help Clyde into the boat.
They then returned to station and, where Mrs Brooks was reunited with her treasured pet.
She hailed the crew for their help.
Spirit of Berkhamsted was refuelled and ready for service at 4.45pm.
