I had a puppy puke up worms at 6 weeks. The vet would only deworm for one worm at a time because he was worried about to many dying off at once and causing a blockage. I would absolutely not screw around deworming her myself and take that chance. I still remember how concerned that vet was. I could not believe the amount and size of the worms that came out of her little body. Call your vet in the morning.
