But no one noticed that the dog also had a very strange, secret routine. At 7, every morning and evening, she would jump into the flooded Yangtze River and swim more than two kilometres to an isolated island. 
Huang Pinghui, a swimmer and Tai Chi devotee was the one to discover the dog’s secret mission. One day when Huang was doing his routine exercise of swimming across the River, he took a rest at an island called Shanhuba. Since the Yangtze River flooded in June, the island had been isolated, thus becoming rest land for many swimmers like Huang. On this no man's land, Huang Pinghui was surprised to find four, new born puppies. 
 The next evening, when Huang arrived at the island again, he saw a dog swim come swimming. He immediately understood how the four puppies had got there. The dog had given birth to the puppies on Shanhuba. But after the flood had isolated it, the family was trapped on it. To hunt for food for herself, the mother had to swim to the land, but every day, she came back twice to feed the babies. She also spent the night with them. The new mother was swimming 8 kilometres everyday to keep her babies alive!
Huang realized that the dog had been doing this for over two weeks now. He was so moved by the effort that he wrote the story down, named the dog Hua Hua and asked a friend to post it up on a pet website.
 As the locals got to hear of the heroic mother’s story, they brought meat and food to her so that she would be nourished to nurse her young. Some went a step further and started to give Hua Hua a ride in their boat!  
 It is a well documented fact that animal moms are as devoted as human parents and would go to any lengths to protect their young.
In 1996, the story of a Brooklyn cat named Scarlet touched the hearts of people throughout the world. An abandoned building was ablaze and as people watched on in disbelief, the mother cat entered the building five times to pull out her five kittens, one by one, to safety. In the process every hair of the cat’s body was singed.
 Her eyes were blistered shut and her paws were burned. But miraculously, she and four of the kittens survived!
In the United Kingdom, a cow named Blackie and her calf were separated when they were sold separately at an auction to two different farmers. That night thee distraught mother broke out of her enclosure and was found seven miles away on another farm, contentedly suckling her calf! Blackie had jumped a gate and managed the long trek through the dark to find her baby.
