Niall Harbison is a dog hero based in Thailand. He spends his days feeding, caring for and rescuing the many street dogs he comes across. Originally from Dublin, Niall was the owner of a successful advertising company. After selling it, he moved to Thailand where his addictions – drugs and alcohol – almost got the better of him. One day he woke up in hospital, close to death, and realised that something had to change. And that was what spurred him on to start saving and helping street dogs. His aim is to help 10,000 street dogs. This is his story.
