My name is Wendy and I often contribute here on TripAdvisor. On this forum we are constantly being asked about the dogs in Costa Rica and what people can do to help. There are many great organizations in CR but I know that many people like to bring down things for donation (vs giving money to somebody they don't know). That said, I just wanted to throw out some items that one of the large organizations said they are in need of (and this should be for all of them) so here goes:
Medicines for pain
Somebody even once brought down a bunch of sutures for doing sticthes because they were in the medical field and had access to that. :-)
The list goes on...
Wherever you are planning to visit, find the local organization near you and they would be happy to have your donations. :-) If you have any questions please feel free to e-mail me and I will be happy to help. Have a great day everyone!!! Pura Vida!
