Happy Dogs Koh Chang

My name is Tina, I am of German origin and have been living in Thailand since 2004. The first 4 years in Samui, Koh Chang became home to me in 2008 and ever since I have care for those that have no voice, the stray dogs and cats of the island. Happy Dogs Koh Chang was founded in 2012 to reach out to animal lovers world wide for support in helping and saving the island’s stray dogs and cats.

My main goal is spay/neuter to control the population of companion animals in an ethical and humane way. Relying entirely on donations, we need help and support from animal lovers such as yourself. Your support is mandatory to keep the dogs of Koh Chang alive, safe, happy and healthy.

It is heartwarming to see more and more people supporting us by following us on FB and Instagram, sharing about us  widely and supporting our tireless efforts fund-wise and with donations of food and doggy stuff. I am very grateful to have supporters helping with fostering, adopting and sponsoring our in-house dogs!

Making the island a better place for dogs and cats, relieving the suffering and pain of the animals on Koh Chang and to stop the barbaric and sadly common poisoning through education, sterilization and care was my main intention to start the project. As an organization founded purely from a heart of compassion for the countless number of suffering strays on the island, I won’t ever stop to give the voiceless, my voice.

Firstly the mission is to help the dogs and cats that no one cares for. Spay and neuter, feeding, treating, healing, first aid for the sick and injured. Offering shelter for the neglect and abandoned and all those that can’t fend for themselves on the streets and of course adoptions. We have been quite successful over the past years homing our cuties to amazing homes and this is also one of my priorities – finding forever loving homes for our adorable, well socialized former strays.

Keeping the population of stray animals on the island down by means of the realization of humane spaying and neutering programs, was and still is a major priority to start with.
