In FL you are protected against civil action after legally defending yourself from a human but not a dog.
My process and yes I have been attacked.
Yell and stand my ground while not looking in the dogs eyes.
Depending on the size of the dog or aggressive nature I would draw my gun as I was yelling(hopefully the owner would be around at this point).
The next part will be me either having words with the owner or a click bang for the dog.
Have a plan in place because its tough to devise one once you have been bitten because the plan then is usually to kick punch and scream like a school girl
Some dogs are just vocal and not aggressive. My dog will bark at you right up to the point where she licks you to death.
