Can I Get Worms From My Dog: Zoonotic Risks, Transmission Routes, and Prevention

Can I get worms from my dog is a question with a nuanced answer — yes, certain parasites carried by dogs can infect humans, but the transmission routes are specific and preventable with basic hygiene and routine parasite control. Can I get worms from my dog sleeping in my bed is the version that surfaces most often, and the honest answer is that bed-sharing does increase exposure risk for certain parasites, particularly roundworms and hookworms. Can you get worms from your dog through casual petting or normal handling is exceedingly unlikely — the risk is highest through contact with contaminated feces, contaminated soil, or grooming a dog with fecal material on its coat. Dog worms in humans represent a category of zoonotic infections that include toxocariasis (from roundworms), cutaneous larva migrans (from hookworms), and dipylidiasis (from tapeworms). Dog worms in humans symptoms vary by parasite species and the organ system affected, ranging from mild gastrointestinal discomfort to visceral migration causing organ damage in severe cases.

Which Dog Worms Can Infect Humans

Roundworms (Toxocara canis)

Toxocara roundworm eggs are shed in dog feces and become infective in soil within 2 to 4 weeks. Human infection — toxocariasis — occurs through accidental ingestion of infective eggs, typically via contaminated soil contact followed by hand-to-mouth transfer. Children playing in areas contaminated with dog feces are the highest-risk group. In humans, Toxocara larvae migrate through organs (visceral larva migrans) or the eye (ocular larva migrans), causing symptoms ranging from mild fever and eosinophilia to vision loss in severe cases. Proper handwashing after soil contact and prompt fecal pickup reduce exposure dramatically.

Hookworms (Ancylostoma and Uncinaria)

Dog hookworm larvae can penetrate human skin on contact with contaminated soil or sand — a condition called cutaneous larva migrans. The larvae migrate under the skin, causing a distinctive raised, itching track that progresses over days. This condition is self-limiting in most cases but requires antiparasitic treatment to clear. Walking barefoot on sand or soil frequented by dogs at risk for hookworm infection, particularly in tropical or subtropical regions, is the primary exposure route.

Tapeworms (Dipylidium caninum)

Human infection with the dog tapeworm requires ingesting an infected flea. This most commonly affects young children who accidentally ingest a flea while playing with a dog. Infection is easily treated with praziquantel and prevented by maintaining comprehensive flea control on all household pets.

Reducing Zoonotic Parasite Risk

A comprehensive parasite prevention approach includes: monthly broad-spectrum deworming or heartworm prevention with anthelmintic coverage for dogs that spend time outdoors; prompt fecal pickup from yard and public spaces; handwashing after handling feces or gardening in potentially contaminated soil; and keeping dogs with active intestinal infections off furniture and beds until treatment is complete. Annual fecal exams through your veterinarian detect infections before they become heavy enough to create significant environmental contamination. Bed-sharing with a dog on year-round parasite prevention and under regular veterinary care carries minimal zoonotic risk for healthy adults.

Worm transmission from dogs to humans is preventable with routine veterinary care, consistent parasite prevention, and basic hygiene. The risk is real but manageable — it should not deter responsible owners from appropriate pet-owner interactions.
