My niece, who is a Peace Corps worker in the Dominican Republic, found a litter of puppies at the bottom of a 10-foot deep latrine after someone had clearly tried to get rid of them. She learned they had been down there for 3 days, and she worked to save them before it dawned on her that the "owners" of the puppies (who were working with her to "save" the dogs) were probably the folks who shoved them down a hole to die. Long story short, she has now adopted one of the pups which is about 8 weeks old.
I have given her some very basic information about vaccine schedules, worming, crates, dog food, and socialization, but since there are no fenced yards where she lives, and dogs roam free, the real issue comes down to vehicle and other mishap, and disease. Socialization will happen on its own as there are a lot of dogs and people about. The truth of the matter is that most village dogs end up surprisingly placid and non-neurotic. As dog trainer Marc Goldberg recently observed while touring Thailand: "In countries where people are not crazy about dogs, dogs are not crazy."
