I think this can also be linked to her being away from momma so young. Momma didn't get a chance to teach her doggy manners, but fortunately your baby has an awesome human momma to teach her things! If you don't want her doing this behavior, just take the toy away, tell her "no" when she does it and redirect her to a different activity. It will eventually fade away if your consistent.
