I have learned, through unfortunate experience, that when a dog is running at me, I have to scream as I run away, or the dog owner does not notice or care. The last time this happend (~October), I remember making the conscious thought that I need to spare breath to scream as I ran.

I don't give a fuck if your dog is "friendly". I want it under your control and away from me.

Also all those dogs that have chased me are off leash, and there have been local (and building) leash laws in all of those places. So. Also maybe obey the law????
