Meet the hero pet dog that sprang into action to help his owner as he was attacked in the street.

Ten-year-old German Shepherd ‘Beer’ can hardly walk but raced over to help Decha Kieow Ngaam, 57, when he battered by a thug.

The intruder stormed into Decha’s motorcycle repair shop and smashed him over the head with a wooden stick before they grappled in the street.

As Decha’s wife screamed for help, none of the neighbours came to assistance in Samut Prakan, Thailand.

But loyal pooch Beer - who suffered from crippling arthritis - raced over and bravely tried to tackle drug-crazed attacker Surasak Kanthana, 27.

CCTV captured Beer nipping at the thug’s leg and desperately trying to come between him and owner Decha during the attack on November 3 at 6:15pm.

With beer braking furiously, the attacker eventually fled into the night before cops tracked him down a few days later.

Decha, who suffered cuts and bruised ribs in the attack, said that Beer was a ‘’superhero dog’’.

He said: ‘’Nobody else came to help me. Beer is old, he has arthritis and other ailments. But he was there for me when I was in danger.

‘’He could have been badly hurt if the man had hit him. But Beer put his life in danger for me, he is super hero.

''The man was much younger and stronger than me but I fought back.

‘’Beer ran into street to help me. We were like a tag team. He injured me but we won because the man ran away.’'

Police checked CCTV and identified the attacker who admitted being high on drink and drugs when he attacked the man.
