A mother dog carried a puppy to safety through a flood in southern Thailand.

A local was filming the flood situation in her neighbourhood when she saw the canine bringing her white pup to safety, away from a flooded bridge in Trang.

The pooch can be seen slowly stepping into the murky water while grasping her motionless baby in her jaw on November 26.

The filmer said: 'The mother dog and her puppy are safe and they have already been taken in by someone who offered to care for them.'

The death toll from the disaster has climbed to more than as catastrophic floods, described by Prime Minister Anutin Charnvirakul as 'the worst flooding in 15 years', swept through southern Thailand.

Government spokesman Siripong Angkasakulkiat said: 'There have been 33 deaths across seven provinces. Causes of death include being swept away by currents, drowning, electrocution, and landslides.'

Soldiers, volunteers, and local government units have also been mobilised to hasten relief efforts, but they were hobbled by limited phone signal in the area.

The Thai military has sent some 200 boats, 20 helicopters, and its lone aircraft carrier, the Chakri Naruebet, to deliver essential supplies and carry out rescue efforts.

Songkhla's Hat Yai district was among the worst-hit areas, which saw a record 13 inches (335 mm) of rain in a single day on November 21.

Songkhla Governor Ratthasart Chidchoo on Monday declared all 16 districts disaster zones and ordered the immediate evacuation of children, the elderly, and the sick.

On Sunday, high-clearance trucks arrived to evacuate more than 400 tourists from flooded hotels across the city.

The Disaster Prevention and Mitigation Department said that floods hit nine southern provinces, affecting some 1,128,284 households and 3,221,958 people.

The Southern Eastern Meteorological Centre said a strong monsoon trough was causing the heavy rainfall, which was expected to ease this week.

Thailand and neighbouring countries in Southeast Asia are in their annual monsoon rainy season, which sees soaring temperatures followed by powerful rainstorms in the afternoon, leading to widespread flash floods.
