Soldiers rescued a dog stranded on a roof during severe flooding in Thailand.

The officers were evacuating residents when they spotted the frightened animal on top of a home in Songkhla on November 28.

Footage shows a rescuer carefully handing the dog to colleagues waiting on a truck. The team had to lure the pooch with food before they could safely secure it.

A local said: 'The floodwaters had risen high enough to submerge the entire first floor, leaving the dog with no place to stay except the roof.

'It was trapped there without food or water and exposed to strong winds and rain for four to five days.'

The rescuers noticed the mutt's limbs were stiff from exhaustion, but its condition gradually improved after receiving food.

The death toll from catastrophic floods, described by Prime Minister Anutin Charnvirakul as 'the worst flooding in 15 years', has reached 170 people.

Police Lieutenant General Trairong Phiewphan, Deputy Inspector General of the Royal Thai Police, said 104 deceased victims were sent for identification on Thursday evening.

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.
