Hookworms are intestinal parasites that are common in dogs. There are three species of hookworms that affect dogs, and some can also affect humans by migrating through the skin. Hookworms are small, thin worms that are less than an inch long. The appearance of the mouth parts vary by species, but all hookworms have structures (hook-like teeth or plates) to help them attach to the intestinal wall.
