She has actually been this way most of the time, the vet told us that we should not socialize her until she has had all of shots, till the age of 6 months! That really cut down on her socailization! She is now 6 months old and we can not even take her on walks anymore. To people she will:

-Lunge
-Snap
-Jump
-Cry
-Bark
-Stick her back hair up
-And bare her teeth

To dogs she will:

-Lunge
-Snap
-Jump
-Cry
-Bark
-Stick her hair up
-Bare her teeth
-Trys to get off her leash
-Bites people around her or holding her to get to the dog

HELP ME! Actually we do have somebody helping her, but she is still very violent!
