This is the shocking moment a kitesurfer was left needing 18 stitches after being mauled by a pit bull off the coast of Argentina.
Footage filmed on Gustavo Cervino's camera, off the coast of Punta Rasa, in San Clemente del Tuyu, shows the canine heading straight for the kitesurfer as he glides across the water.
The raging dog then leaps into the air and sinks its teeth into Mr Cervino's upper arm before he manages to wrestle the animal off.
During the clip, Mr Cervino can be seen kitesurfing in shallow water when the raging dog suddenly appears and begins to chase him. As the dog bites the kitesurfer, he falls into the water with an anguished look on his face.
The kitesurfer later told reporters: 'I had to open its mouth with my other hand. I do not know why it let me go, maybe because of the water.
'It tried to bite me in the neck but I managed to keep it at bay with my hand.
'If it had bitten me in the neck I wouldn't have lived to tell the tale.'
Reports state the dog continued circling around Mr Cervino after the bite before finally leaving.
Following the attack, the kitesurfer was left with a bleeding arm and had to be helped by a passerby.
The kitesurfer then drove to a nearby hospital where he received 18 stitches to the deep wound on his body.
Mr Cervino added: 'The owner of the dog must have been there. I did not see him because I had to go to the emergency room at the hospital, I had a very deep cut.'
The kitesurfer reported the incident to the police and is now recovering from his injuries. The owner of the dog has not been identified.
