I do have some suggestions and very important ones, as a breeder and owner of a large guard and protect breed.

First is DO not RUN and DO NOT Scream. Both actions are or can be inflammatory to the "attacking" dog. And as a sidenote you will never outrun an attacking dog.

As hard as it may be Stand your ground. ANd stand TALL. Cross your arms up high on your chest - with hands into a fisted position. Here is when opening up an umbrella - or if you have a walking stick is effectively used.

Turn slightly sideways. Using a deep authoritative voice you can say BAD DOG. Never Good Boy!!!! Also quickly try the STOP command. Some dogs will have been trained to this command.

If the dog pauses in its rush - turn slowly slightly more sideways. Ignore the dog, and that can be very hard to do.

Hopefully this will defuse the "attack" and you can go on your shaken way.
