A devoted dog owner has been filmed risking her life as she rushed into freezing waters to save her dog .
The woman disappeared under the water for several seconds while she struggled to rescue her pet, which had been dragged out to sea on Sunday.
Rescue organisations have said she was lucky not to have been killed.
Powerful waves carried her back up the beach as the dog desperately tried to keep its head above water, moments before another wave swept it back inshore.
The fully-clothed woman finally grabbed the floundering animal before she was hit by another wave before a bystander dragged the dog to safety.
