Neglected and mistreated 'street dogs' around the world.... and the man working to save them

Niall Harbison: "In the space of just two and half years, we have amazingly reached 90-95% coverage of dogs sterilised here on the island of Koh Samui... weāve stopped a vast amount of unwanted, unloved and uncared lives being brought into this world."
It all starts, as so many dog rescues do, with my WhatsApp pinging.
A picture message.
I donāt recognise the number itās been sent from, itās not from a friend or a member of the family back home. So I can be pretty sure that the image Iāve received will be of a dog ā and itās probably not going to be a cute āawwwā kind of one.
In those few milliseconds as I wait for it to download, thereās a familiar sense of dread of whateverās coming next. It wasnāt long after getting sober that my mission to save the street dogs in Thailand began. Iāve grown used to the fact that Iām like the fourth emergency service out here. For humans thereās the fire, ambulance and police services ā for dogs, however, well, itās fair to say Iāve become the go-to in that department.
It seems to take an age for the image to become clear.
Living in Koh Samui, a tropical island off the east coast of the country, has many wonderful things going for it ā clear blue skies, fluffy white clouds and luscious jungles to explore. It even has some of the fastest WiFi in the world but today it was taking forever.
A little anxiety seeds in my tummy. Come on then, how bad will it be?
Youād imagine Iād get hardened to seeing upsetting pictures of mistreated animals after all this time. Some are cruelly abused by humans, others were just unlucky enough to be born. Unwanted and unloved by anyone.
Suffering, because the world just isnāt always fair.
Yet despite all the horrible states Iāve found animals in, I never get desensitised. Iām a big softie I suppose, thereās always something that can still shock me, make me wince, or induce flashes of utter fury sometimes. (Never aimed at the poor wretched animal. Iām only ever angry at the humans whoāve neglected them ā or, worse, maliciously inflicted the damage. Or just society as a whole for not caring as we should.)

As the picture on my iPhone finally crystallises with definition, turning from a blurry shape into a clear photograph, I see itās a dog on a chain. The fur is fair, thin and matted in places, while sparse in others; thereās some expanses of sore-looking skin exposed. I peer closer and notice the poor thing has been lying in its own toileting.
Eugh.
But the dogās face is long and noble somehow, and poking out from the fur obscuring the poor thingās vision are the most vulnerable-looking dark eyes Iāve ever seen.
The expression is of complete dejection, one of the saddest-looking animals Iāve ever seen. I groan audibly and put my head in my hands briefly.
It is impossible to tell the breed of the mutt from the picture, and letās be honest the ābreedsā in Thailand are way more loosely based on the intended breed. Most of the dogs out here in Koh Samui are a mix-up of all sorts as theyāve haphazardly mated on the street and multiplied (and multiplied, and multiplied ā¦). All sorts of doggy DNA exists, born by accident and not design.
And in my opinion theyāre just as beautiful as any pooch who might be showcased at glamorous dog shows like Crufts in the UK or the National Dog Show in the US. And their life is every bit as valuable. I just wish there werenāt quite so many of them.
I read the rest of the text that follows the picture.
This particular poor mite had been spotted by a tourist in the mountains earlier that morning. That part of the island isnāt one I was so familiar with. I have to admit, I still donāt know every corner of Koh Samui. (The fact that for the first couple of years of living in this paradise I was mostly steaming drunk definitely didnāt help me in that regard.)
I rub my eyes again. God, Iām knackered. I want my dinner, I want a shower, and I want to curl up on the sofa with my own dog Snoop. But this is one of those moments when you just know you have to drop everything. Just go, Niall. I know in every bone of my body that here is a dog in dire need; he or she simply could not spend another night in that miserable dirty state.
Whoever it belongs to, and however it got there, I need to go and help it. Immediately.
Spring was fast approaching and Tina had long settled in and had really seemed to be thriving. She was well enough, we decided, to have a sterilisation operation. It was espe cially important to have that taken care of now that she was out and about having fun and socialising with other dogs on our walks.
Tina had spent so many unhappy years being used for breeding puppies, which had completely worn out her body, getting the operation was particularly symbolic and a start of a better future ahead.
Dogs canāt talk to us but they can to each other.

You can clearly see Hank here looking on and telling her itāll be ok here. And itās clear Chance knows that too.

I felt incredibly proud of her as I got her ready to be sent off to the vets, like we did with all the others. It was hard to know exactly how old she was, to tell you the truth, but the vet guessed around eight, which meant she could still technically get pregnant, and that was the very last thing Tina needed ā or any of us for that matter.
It might seem like a small footnote in the bigger scheme of things for Tina, but it still felt like a significant moment of closure for this wonderful lady.
āDonāt you worry, angel,ā I kissed her affectionately on her wet snout before she went under the general
anaesthetic. āWeāre just making sure you never have to have another puppy in your life again.ā Not only would her ill health not have coped with a pregnancy, but I felt she deserved to just focus on being a dog for the first time in her life, and sharing all the amazing love and affection she had to give.
To be very precise Tina was the 521st dog we have sterilised since starting this mission to solve the street dog problems in Thailand. And yes, I really do keep count of each and every one, as it just means so much to me. I used to keep a count in my head but now Iāve developed a helpful spreadsheet. I know their little quirks, like who doesnāt like the rain, or who needs their skin checked during the wet season. When a dog is walking a little gingerly, I can look at them and know if itās serious or not. If they are a little underweight or need to see a vet.
I donāt have kids but I guess this is a similar way parents would know through intuition about their kids. With 80 dogs to look after, I know the odds are stacked against me in terms of keeping them all healthy and alive, but they are my pride and joy. I think of it as having 80 pets that happen to live on the streets.
I think thereās 500 million street dogs in the world ā thatās more than the population of America ā and I want to halve that in my lifetime. Sounds crazy, but I think I can do it, and Iām really proud of the fact that we now have eight other partners in three countries, not just Thailand but Sri Lanka and Indonesia, too.
Until as recently as 2022, I wasnāt even aware of what neutering was. In the space of just two and half years, we have amazingly reached 90-95% coverage of dogs sterilised here on the island of Koh Samui.
We can never get to having 100% of the dogs sterilised in any given area because some locals wonāt allow their dogs to be done; there are still, sadly, some dog breeders who want to make money from puppies, and dogs are still being brought in by workers. But weāve stopped a vast amount of unwanted, unloved and uncared lives being brought into this world.
