Walking along the beach they, a father and his son, heard a dog barking for help.

Looking around they found a Dobermann trapped in the rocks. They tried for half an hour to help the dog but to avail.

A 911 call brought a quick response.

Two firefighter crews launched a rescue operation for the dog who soon was free and safe.

They think the dog went in to sniff around the large boulders but, once the tide came in, had been unable to get out again.
