Answer:
Wolf pups are fiercely guarded by their parents and the entire pack----except for man, there really aren't any other animals who would mess with them. Wolves have extremely good senses of smell, and they will use that sense of smell to help them avoid areas where there are other wolf packs or larger predators. Because of deforestation, though, wolves are often forced into human environments. This is the main time when humans will kill them.
