This is the dramatic moment a frantic mother dog tore apart mats to free her puppy who was stuck in the cage railings.

The distressed brown pooch spotted her baby writhing around crying for help while trapped in the metal enclosure in Loei, Thailand, on June 16.

He had wedged himself under the purple mat and at risk of suffocating from the weight pressing down on his tiny body.

Footage shows the canine tearing the purple mat off and barking loudly to get its owner's attention.

The owner, who was not at home, saw the incident on CCTV, prompting her to return immediately.

Fortunately, with one final effort, the worried mother dog managed to tug her puppy out. She's seen on the video rolling him around on the ground to rouse him as a precaution in case he was unconscious.

The owner returned and checked on the animals. Neither of them were hurt.
