Pet dogs chased away a monitor lizard that charged into their owner's front yard.

Footage shows the pooches standing guard to keep the reptile from advancing further into the residential property in Surin, northeast Thailand, on May 18.

The canines tried to attack the animal but were stopped by their owner, who let it escape unharmed.

Asian water monitor lizards normally live in canals, swamps, sewers and ponds in cities in Thailand. They feed on fish, snakes, frogs and scraps of food left by humans.

The reptiles are aggressive when threatened and have a mildly venomous bite which sometimes carries harmful bacteria. The Godzilla-like reptiles are also a protected species in the country so their population thrives.
