About us

Who We Are

We are ANIMAL RIGHT ACTIVISTS and veterinarians who aim to make Koh Chang a BETTER PLACE for animals. All work with full passion for animals. It has nothing to do with a Job. Its also more then a hobby its a WAY OF LIFE. A close COOPORATION with the authorities and communities is a matter of course for us. We are very GREATFUL for their constant SUPPORT. At the request of the authorities, our name was changed from Animal Voice Koh Chang to ANIMAL WELFARE KOH CHANG ORGANISATION when we registered as a LEGAL organization in 2023.


About Us

Since  2011 MO HERBIER, has been committed to helping animals in need on the beautiful island of Koh Chang. On the other side TANJA SIEGWART and her registered Swiss Association “Tierschutz für vergessene Seelen” were STERILIZING animals on Koh Chang FREE OF CHARGE since 2015.

Since 2019, the two animal welfare protectors joined forces. TOGETHER they have the goal to spay/ neuter all unwanted animals on Koh Chang to prevent misery. MO HERBIER is a local animal welfare activist and NATIVE THAI who has close ties with the authorities and even works for the veterinary office.

In 2023 the registered Thai Organisation Animal Welfare Koh Chang has been founded by Mo and Tanja. These synergies are bearing fruits. And to this day, both founders & friends still see their main task in spaying and neutering as many animals as possible.

From our point of view, if we can CONTROL the amount of unwanted animals we can provide better care to all animals, who are not fortunate enough to have a family to love and care for them. This will IMPROVE the situation for ALL of Koh Changs forgotten furry friends! 

Our Teams

Everything can be well organized. But if you don’t have a GREAT TEAM, you can’t work well. That’s why we are so grateful to have our incredibly MOTIVATED colleagues and volunteers. Be it on the STREET or at our HELP POINT. They all have their HEARTS in the RIGHT PLACE. They work until they drop, nothing is too much for them.

We are well aware that there would be no Animal Welfare Koh Chang without these LOVELEY PEOPLE.

Help us

While Koh Chang, the second largest island in Thailand, is best known for its beautiful temples, beaches and delicious cuisine, it hides a DARK SECRET. Many stray dogs and cats can be found through out the island’s; streets, beaches, temples, and jungle areas. It is most obvious when following the sunset. After witnessing the MASSIVE NUMBER of stray animals that can be seen at night, you can better grasp the severity of the situation. This has been brought on by several factors. One being BUDDHIST practicing the belief of showing love and kindness to every living creature.  Feeding stray animals is a way to practice this. This act of KINDNESS helps dogs and cats survive, but it also causes them to reproduce more successfully. Coupled with very limited inexpensive options for STERILIZATION, countless unwanted puppies are born every year.

Due to the lack of medical care, this ever growing  population of UNWANTED animals become more exposed to and prone to suffer from infectious diseases and parasites. Koh Chang is home to THOUSEND of stray dogs and cats who SUFFER from:

  • traffic accidents
  • malnutrition and hunger
  • poisoning
  • abandonment mainly due to “owners” moving away
  • drowning during monsoon season

STERILISATION is the most humane way to control the unwanted animal population.  Animal Welfare Koh Chang has made it their Primary GOAL to REDUCE the MISERY of  these animals by these means. Since Koh Chang is an island, we have  an excellent chance of SUCCESS.

All animal lovers together are Animal Welfare Koh Chang
Together we can be the voice for animals in need!
