Dogs can be unpredictable, and they're powerful animals. They could start fighting with another dog, run away and endanger themselves, do their needs in someone's front garden, eat something dangerous, or someone else walking by might be scared of dogs. I have seen occurrences of all of these situations. It's really irresponsible to walk a dog unleashed, especially in populated areas.
