What is best wormer to use on two week old pups?

Nemex-2

Start at the 14 day birthday and de-worm weekly after that till ten weeks of age. this helps to keep the puppies healthy. Strongid and Panacur...Panacur after they get a little age on them.

go to the Walmart and buy human wormer lots stronger than nemex look at memex bottle and adjust dose also lots cheaper
