Very agressive behavoir

Question
 I have 3 german shepereds 1 saint Bernard,  My female shep is very agressive towards other animals out side the fence.  And I don't know if she would bite anyone but she might.  I have 4 kids and she is very good with them and anybody who comes into the house.  But when she is out side and can see somthing people or animals she wants out to attack what ever it is.  My othe two shep's are great.  Very friendly.(Both males).  The Saint Bernard is very friendly.(female).  I don't want to get ride of her but I'm going to have to if this keep s up. She is going to be 2 years old.  What do I do.  And How do I do It.  And who would I give her to.
   Thank's for your time.

Answer
HI SCOTT
IT WOULD BE WORTH YOUR WHILE TO GET THE INVISABLE FENCING FOR THIS DOG TO SHOCK HER TO NOT GO THAT NEAR THAT FENCE.
SHE HAS DEVELOPED A BAD HABIT OF JUST ACTING BAD BECAUSE THEY ARE OUT AND SHE IS INSIDE.  SOME DOGS OUT OF PURE BOREDOM DO THIS AND SOME MEAN IT.
IF SHE IS GOOD WITH YOUR KIDS, I FEEL SHE IS JUST RUNNING OFF STEAM TRYING TO SCARE PEOPLE OR DOGS.
WALK HER DAILY FOR EVEN JUST TEN MINUTES BY HERSELF AND SEE HOW SHE ACTS WHEN SHE SEES A DOG.  IF SHE DOES AND STARTS TO FUSS, PUT HER IN A SIT COMMAND UNTIL IT PASSES, SQUEEZE HER NOSE AND TELL HER NO NO LOUDLY.
IF YOU WORK WITH HER ON LEASH OUTSIDE THE FENCE OR YARD U CAN BREAK HER OF THIS.
ALSO, U CAN GET A SPRAY WATER BOTTLE, PUT A TAD BIT OF VINEGAR IN IT, SPRAY INTO HER FACE EACH TIME SHE DOES THIS AND I FEEL THIS MIGHT STOP HER QUICKLY.
I WOULD NOT RID OF HER BECAUSE SHE IS FENCED IN, MAKE SURE YOU GET ONCE A WEEK A RAW BEEF SOUP BONE FOR THEM TO CHEW ON.  KEEP AN EYE ON THE KIDS WHEN DOGS HAVE BONES.  SHE IS YET A PUPPY AT TWO AND SHE IS WORTH CORRECTING.  IF U REALLY WANT TO RID OF HER PLACE AN AD IN A PAPER OR POST SIGNS MADE BY YOU FOR A TWO YEAR OLD FEMALE WITH GOOD TEMPERMENT THAT NEEDS A GOOD HOME, MUST GIVE HER GOOD ATTENTION AND EXPLAIN WHY YOUR FINDING HER A HOME, MAKE SURE THEY AGREE TO DAILY EXERCISE HER FOR BEING IN A YARD IS NOT EXERCISE LIKE RUNNING IN A FIELD, OR WALKING OR RUNNING ALONG SIDE A BIKE.
