Yes, I have read the links you've posted. I've always corrected her bad behavior but she always seems to revert back to her bad behavior the next day.
The bad behavior will not go away after only one day... you
have to stay
consistent with your corrections, it may take at least a few weeks to correct her behavior. My suggestion would be to pick one way of correcting (it might have to be a little more harsh than just saying "oww", like a pop to the collar or something) and
stick with it. Also, keep her away from the children until the behavior is corrected. You don't want an accident to happen and have something happen to your dog. Kids can exaggerate things, and puppies can hurt kids easily. Keep them separated and work on your pup's behavior by yourself, if you involve too many people, she might get confused. Please, don't give up so easliy and resort to getting rid of her, you're only going to make her behavior worse by re-homing her or bringing her to a shelter, and she could end up being put to sleep because of it. You wouldn't give up on a human child, would you?
