How long does it take for dog worms to die after treatment?
It can take as little as two hours for the worms to start dying off. However, in most cases, the process starts about 12 hours after administering the dewormer. You may continue to see worms in your pup's poop for about a week. If they had a serious infestation, you may see worms for up to two weeks.
Do puppy worms die when they come out?

How do I know if dewormer is working on puppy?

Additionally, an improvement in overall health and physical appearance can indicate that your dog's dewormer is working and that worms are leaving her body.
