This brave dog showed he was not afraid of snakes - barking at a serpent as it lunged at him with fangs bared.<br /><br />The five-year-old pooch named Mon spotted the vicious rat snake outside his owner's house in Saraburi, central Thailand, on Tuesday (August 27) afternoon.<br /><br />Dog owner Chattaphon watched as his protective mutt went eye-to-eye with the snake, which rose up with its mouth spread wide open.<br /><br />The rat snake leapt towards the dog several times in an attempt to defend itself by biting it. But the nimble pooch backed away and returned with its aggressive barking.<br /><br />The snake - harmless to humans but deadly to smaller animals - was eventually forced with slither away in defeat.<br /><br />Chattaphon said: ''It's good to know that my dog will always protect me against snakes. <br /><br />"I just hope that he's never bitten by something more dangerous.''
