Inside the dog’s small intestine, adult female hookworms release eggs.

Eggs are released in feces approximately 10-21 days after infection.

Feces contaminates soil in your yard where immature worms develop from the eggs in about a week.

By walking or playing where dogs frequent, immature worms can infect humans through exposure to unprotected skin.

Contaminated soil on toys or dog’s paws may put the dog at risk of infection if ingested.

Immature worms can remain dormant in your dog’s skeletal muscle.

Skin may be penetrated by immature worms in contaminated soil.

A puppy may become infected through milk when larvae migrate to their mother’s mammary glands.
