Max, a Newfoundland, had gone in the water for a quick dip, but became entangled in a barbed wire fence.
Owners Irene and Stewart called 999 and asked for the Coastguard and Newhaven coastguard rescue team, along with East Sussex Fire and Rescue Service were quickly on scene.
Max was cut free and, once rescued, was keen to continue exploring with his βNewfoundβ emergency service friends.
