A good samaritan from Louisiana took to the deadly floods in a bid to rescue anyone and anything he could.

To his surprise he stumbled across an abandoned dog who was just minutes away from drowning.

Josh Petit took to Facebook to explain that his boat was skimming over several feet of water on Monday after flash flooding had hit the city.

The kind man spotted a bush shaking, looked over and saw a grey muzzle and a pair of frightened eyes staring up at him – it was a frightened dog, it’s body submerged in muddy waters.

He wrote on Love What Matters Facebook page: “The dog could barely tread water anymore she was so worn out and had the saddest eyes I ever seen so scared for her life! We saved her and she came laid her head on my lap and cried and moaned like a big baby! She was thanking me. I thank God for letting me notice her.”

After the successful rescue, Josh took the dog to a flooded vets along with his own pets.

The dog then stayed with the vet in a bid to find her owners.

And later on a miracle happened – the dog’s owner was located.

It turns out the canine’s name is Sadie and the owner said she was spooked and ran off as they were loading another dog into the car.

After hours of searching the owners were unable to find her, having no choice but to leave.

As the town was flooded so quickly, many people had to leave their beloved pets behind in a panic or pets ran off in terror – as Sadie did.

The post received over 50,000 likes leading to people sharing their own stories about the floods.

One lady even said she thinks she had also seen Sadie a few days before, she fed her and gave her some water, but eventually the lost dog took off.

The rain started in Louisiana on August 12 and so far has dropped four billion gallons of water on low-lying areas.

It is thought the floods have destroyed at least 40,000 homes and 70,000 people have registered with FEMA for disaster assistance.
