Hookworms can enter the body of animals or even humans. The hookworm attaches to the lining of the intestinal wall and feeds on blood. Its eggs are ejected into the digestive tract and the larvae (young hookworms) that hatch live off of the host’s blood. The host can suffer from blood loss, anemia and iron deficiency.
