How long do you have to wait to de-worm a new born puppy?

2nd Answer:

You should do your first deworming at around 4 weeks of age and be sure to de-worm Mom at the same time too. Most all pups have roundworms but they could also have hookworms, whipworms, etc. so best to de-worm them starting at 4 weeks, then repeat at 6 weeks and once again at 8 weeks. Bring in a fecal sample to your Veterinarian to have it checked out for parasites, just combine a small sample from most of the pups and mix it together.
