There are over 100,000 stray dogs in Bangkok and they usually deal with the problem by poisoning them. Some of my students decided they wanted to help these dogs, so they raised some money for an organization that works for them.
They have their programs suspended right now because the local community does not like all the noise (who can blame them). They are planning to open one of two new facilities to get things going next month. I think the education part of the program is most important since a thousand or so spays and neuters will have a limited impact on a 100k animal population that is growing due to discarded animals.
Nice people, good cause, good visit.
