CS spray, that was issued to the police initially although down the line a bit it was changed to pepper spray, doesn't work, at least not effectively. Our trainers said that spraying in the face might have some effect because dogs don't like being sprayed with liquid in the face. But in full attack mode, I wouldn't like to depend on that.
Basically, find a weapon. Preferably a long and wieldy something to keep the dog at bay. A piece of iron, a hefty frying pan or similar. Metal is good, the dog can't latch onto it as much as wood.
However, there are some dogs that if they get latched onto you, you are going to have a real problem. Pit bulls and similar breeds. I'm sure some will recall (I think it was in London) police went to a house for reasons I can't remember and the dog there latched onto an officer's arm, injuring it badly and continuing to injure. Nothing they did could shift it. Eventually one of the cops used his firearm and shot it. There was an awful hue and cry about that!
Dogs are, of course very good at discerning people's state of mind. A smile and some kind words delivered confidently often works. Defensive postures, sudden awkward movements, screaming and shouting and running away encourages the opposite. Doesn't always work though. But you can usually tell people who "don't like dogs."
