How to stop my dog trying to attack people in the street or who come to my home?

bit of a shot in the dark, but i think the dog may see you as it s puppy,and she must protect you ,if i am right, you must show the dog that you are the alpha ,do not talk to the dog when you get home for a few min s or when you leave just go ,eat first ,take her food away and give it back ,make hear get ot of her bed and you sit in it , go through the door s first , she must walk behind you ,as soon as she look s at another dog when walking her ,swing your right foot behind the left at tap the dog on the rump and command no ,you could muzzle,her and take her to a dog show and put her among hundred s of dog s and people ,it will take a lot of work as she is some what programed i think you will need to be very firm to somewhat hard on her, to show her you are her boss, and a fair one at that. good luck
