My dog vomits and passes roundworms; how many days until the dewormer works, should I deworm daily, how many doses per day, and why no effect yet?
Vomiting or passing roundworms means a worm infection; dewormers kill or expel them. Effects start within hours but full expulsion can take days. For an active infection, dose once the same day by weight, then re-deworm if worms persist until cleared; preventive deworming is monthly. No effect may mean wrong dose, poor product, or wrong drug for the worm type, or secondary enteritis/parvo, so see a vet.

Roundworms in a dog's stomach generally do not cause death unless there are large numbers of worms or they are left untreated, leading to the release of toxins or severe intestinal blockage. Even in such cases, the exact time of death cannot be determined. Owners should deworm their dogs regularly to prevent prolonged roundworm infection.
