Soi Dog Foundation: Changing the Fate of Strays, One Life at a Time

Founded in 2003 right here in Phuket, Soi Dog Foundation was born out of a deep need — and an even deeper compassion. At the time, over 50,000 street dogs and cats roamed the island, unloved, uncared for, and multiplying rapidly in the absence of any real solution. Soi Dog stepped in with a mission: to offer a humane, sustainable answer to the street animal crisis through sterilization, rescue, and medical care.

And we’ve never looked back.

Thanks entirely to support from compassionate individuals around the world, Soi Dog continues to operate without government funding — just heart, grit, and a global community that believes animals deserve better.

What We Do

Every year, Soi Dog sterilizes and vaccinates tens of thousands of street dogs and cats across Phuket, Bangkok, and other parts of Thailand. To date, we’ve sterilized over 199,000 animals — and counting.

Our approach is hands-on and holistic:

• Spay/neuter programs to break the cycle of suffering.

• Medical treatment, vaccination, and shelter for those who need more than the streets can offer.

• Adoption programs that connect animals with loving forever homes.

• Mobile sterilization units, now rolling through the Bangkok metro area — a monumental project targeting the estimated 640,000 street dogs there. It’s a seven-year mission backed by science and compassion.

The result? Phuket’s street animal population is now officially under control. And by 2025, you may rarely see a stray on our island’s beaches and streets — not because they’ve disappeared, but because we’ve done the work to prevent suffering before it starts.

Beyond Phuket: Fighting Cruelty Across Asia

Soi Dog also stands on the frontlines of animal welfare advocacy throughout Asia:

• We’ve helped shut down the dog meat trade in Thailand and continue to fight it in South Korea, Vietnam, and beyond.

• We respond in times of crisis — from the 2004 tsunami to major floods in Bangkok and southern Thailand.

• As a founding member of the Asia Canine Protection Alliance, we work with regional governments to combat rabies and campaign for laws that protect dogs and cats from the meat trade and other abuses.

Our Vision

A society without homeless animals. A world where cruelty has no place. A better life — not just for dogs and cats, but for the people who live alongside them.

Join us. Support us. Because every dog deserves a chance. And every cat deserves a safe place to curl up at night.
