By learning about these infections and how to prevent them, you can help protect your pets, yourself, and your family. Dogs and cats with these worms pass worm eggs or larvae in their feces poop.

However, in some cases they can cause damage to tissue. Sometimes they affect the nerves or even make their way to the eyes. In some cases, they may cause permanent nerve or eye damage, even blindness. Hookworm larvae typically move around within the skin causing inflammation and red, itchy tracks in the affected skin.
