Is my bulldog aggresive?!

Question
I have had my baby english bulldog for about 3 months now. And for about 1 hour each day she goes into a "crazy" mode. She will start barking and trying to bite at me and my wife. We play fetch and other games with her to she is not bored with us, but about 15min into a game she no longer wants her toy. It seems like all she cares about is tasting my ! My dog trainer said it was normal and she is still young and doesnt know how to play with you yet. Is there anything I can do to prevent causing aggresive behavior within my bullie?? And if she is a more aggresive puppy is there anything I can do to stop it? Thanx!

HI DAVE
I HAVE YET TO SEE A NASTEY ENG, BULL DOG.?  THEY ARE COUCH POTATOES, A DAILY WALK WOULD HELP ALSO.  I WALKED BRITA SO MUCH AS A PUPPY SHE WAS ALWAYS TIRED ALONG WITH MY BOSTON.
U MIGHT GET A SPRAY BOTTLE OF WATER ADD A TAD BIT OF VINEGAR IN IT AND SPRY HER FACE IF SHE GETS TOO BAD?
SHE IS JUST BEING PLAYFUL AND GETS A SPURT OF ENERGY, BE HAPPY FOR THEY ARE AT TIMES TOO LAID BACK AND LAZY.
WHAT SUPER PETS THEY ARE MINE LOVED KIDS.  WE JUST PUT HER DOWN OCT 13 DUE TO OLD AGE OF NEAR 12 LIFESPAN IS ONLY 8 ON THEM.
OTHER THAN POSITIVE TRAINING, HAND HER A TUG OF WAR TOY. GET A ROPE OR OLD SOCK AND HOLD ONE END AND LET HER LEARN TO PULL, BRITA LOVED THIS AND TAUGHT MY SHEPHERDS HOW TO PLAY.
