There is a dog in my neighborhood which seems pretty uncontrollable, breaking out in barks and growls whenever it sees another dog, no matter how distant. It appears to be a pitbull cross, not that it matters, but it's a very large dog. The woman who owns it will start to yell at you to go some other way if you are on the path she means to take. The dog is big enough to drag her if she's not fully braced. I feel like I should report the dog to animal control but there's been no incident yet, although I'm sure there will be for some unfortunate dog in the future. What would you do?
