If she is pooping out worms, that means that the dewormer is working. She may need to be dewormed several times due to the life cycle of the worms. I would also recommend having a fecal exam done at a veterinary clinic since not all dewormers kill all types of worms and parasites. Many pets can be infected with multiple types of worms at the same time.
