{Dogsnaturallymagazine.com Dec. 15, 2021} "Diatomaceous earth can eliminate roundworms, whipworms, pinworms, and hookworms in your dog. It can work in as little as 7 days of daily feeding. But, to be most effective, you should feed diatomaceous earth for at least 30 days. That'll make sure you get rid of all newly hatching eggs."
