A huge lizard tries to claw its way into a home to hunt a small dog quivering inside during incredible video footage.

The giant monitor lizard was caught in the act outside an apartment in the Nonthaburi area of Thailand.

Standing at about 6ft tall, the imposing creature, lured by the presence of the beloved pet, scratches at a door as its prey is heard yelping in terror.

However, the scared hound is not the only one intimidated by the creature - the people filming the hunt scream as the monitor slams its tail back and forth, crashing into the apartment's wall.

Monitor lizards can be found in Africa, Asia and Australia and are carnivores that will eat insects, birds, rodents fish and small mammals.

They are resilient creatures and can live across a wide range of habitats from deserts to forests.

Luckily for the dog, the monitor does not manage to break into the home with a man attempting to put a noose on the beast towards the end of the footage.

During the film - which ends with the giant lizard still by the door - a man can be heard saying: 'It is in our house. It's f***ing huge!'

Then a woman's voice says: 'They say if you throw a coin at it, it will go away! It's like giving the lizard luck and fortune!'
