Donations of time and/or money are hugely appreciated at the aptly named Samui Dog & Cat Rescue Centre. Volunteers are always needed to take care of the animals at their kennel/clinic in Ban Taling Ngam (but not at the smaller Hat Chaweng branch). Call the centre for volunteering details or swing by for additional info. Check the website for directions.
The organisation has played an integral role in keeping the island’s dog population under control through an active spaying and neutering program. The centre also vaccinates dogs against rabies.
