How about running away as fast as you can. Back in my prime of my youth, I could outrun a dog(s), but now, I don't know. . .There's going to be some comments as to how effective or ineffective a flash of light can be on an aggressive dog towards you.
I'd suggest this is really bad advice on both counts.
Running can trigger the prey instinct. This will vary from breed to breed as well as the dog's background.
In general, dogs are MUCH faster than people.
Don't panic. Talk calmly to the dog, avoid making direct eye contact and slowly move away.
I'd say the most importaint thing you can do to protect yourself is to learn more about them and get some hands on experience with larger dogs.
As an owner of larger dogs, it is interesting to see people's reaction to large dogs. I had a large black lab who recently passed away, who went everywhere with me since our company lets us take them to work. This allowed me to observe a lot of strangers reactions in all sort of settings.
Sophie was the most calm, steady and friendly dog you'd ever meet. If someone broke through my bedroom window while I slept she would probably go over and see if he wanted to pet her or if perhaps he had a treat for her.
Yet, I'd see people step back and with obvious alarm, and I've seen out of the corner of my eye darting nervious glances at her. We even had a mailman who mentioned that she looked at him with ill intent in her eyes (or something to that effect).
The funny thing is I know that look well. Sophie was too well behaved to outright beg, but she'd sit politely and look at you hoping to soften you up with her big brown eyes. It was her "look at me, I'm such a good dog, don't you want to give me a treat or pet me?" look.
What's my point? Just don't attribute to malice what you are unfamiliar with.
That said, dogs that are roaming the street are nothing to be taken lightly. If the dog is on the street, you have to assume it's owner (if any) does not take the responsibility of ownership seriously (and many owners don't understand dogs that well, anyway) and you have to assume that it might not be well socialized, etc.
Also, even with a reasonably raised dog, they have strong instincts. This varies somewhat from breed to breed and obviously from dog to dog. It is the dog's owner's responsibility to protect the dog from these instincts and make sure they don't get into situations that the dog doesn't understand (they are dogs after all, not people!) and thus gets in trouble. The sad part is the dog always pays the price.
For example, my guess is most bites are fear bites, not agression related bites. Although, you always hear bites as characterized as from "agressive" dogs.
The danger does go up when there is more than one dog, as the pack instinct really starts to kick in. You see this same type of behavior out of teenagers. You put a pack of them together, and you see behavior that any one of them would have not instigated.
Of course, there are some agressive dogs out there, and from spending a lot of time in the dog park, if I see a dog *looking* for trouble, you can bet it is a pit bull. I'm not sure how much of this is the dog's genetics, or shaped by the personality of the type of people attracted to the breed. I'm not saying there aren't good pit bulls out there, or good pit bull owners, but just that when watching a large number of dogs, this behavior jumps out of the background noise. In any case, there are agressive dogs out there, just like there are seriously bad people out there.
Ok, let's get this back on topic..
If you did have to defend yourself, I wouldn't put much stock in a flashlight. You might give it a shot prior to any other actions, perhaps it might distract it. If the dog is truely agressive and attacks (vs fear attacking), this is *not* going to stop or slow it down. Dogs are incredibly focused and it just isn't going to phase it.
Personally, I would use an escillation of force. Here is what I would could consider against a dog (in order) if I was out walking.
1) OC spray.
2) ASP baton. 6D Mag will substitute OK here.
3) Firearm.
