Hookworms (Ancylostoma) are intestinal parasites that latch onto the intestinal wall and suck blood. They are voracious blood feeders and can cause fatal anemia in puppies.
This condition requires veterinary attention.
If your animal shows the Key or Common signs listed, please visit a clinic immediately.
Report Case / Get HelpLarvae penetrate the skin (feet) or are ingested from soil/milk. Can also infect humans (Cutaneous Larva Migrans).
Larvae migrate through lungs to gut. Adults bite gut wall. Puppies can fade rapidly due to blood loss before eggs are even seen in feces.
Fecal flotation detects eggs. In very young puppies with anemia, treatment is often assumed before eggs appear.
Antiparasitics (Pyrantel, Fenbendazole). Anemic puppies may need a blood transfusion.
Monthly prevention. Cleaning up feces immediately to prevent soil contamination.
Good if treated before severe anemia occurs.
