Cherry Pits are poisonous to dogs. So either the tree comes down or figure out a way to keep her away from them, I wouldn't rely on no in this case. I would get rid of or block the issue. Mine are eating mulberries, I stop them after a few because while they won't kill them, it can cause loose stool.
