The deep bond between humans and their dogs often blurs the lines between pets and family members. This closeness means sharing our lives, homes, and sometimes, unintentionally, microscopic hitchhikers. A common concern among dog owners is: “Can humans get worms from dogs?” This is a valid question, as understanding parasite transmission is key to ensuring the health and well-being of both your canine companions and your family. At Boulder Veterinary Hospital, we are dedicated to providing accurate information to safeguard your pets and yourselves.

Understanding How Worms Transmit from Dogs to Humans
Parasites, including various types of worms, can indeed pass from dogs to humans through several pathways. Recognizing these transmission routes is the first crucial step in effective prevention. Understanding Can Humans Get Worms from Dogs? Understanding Parasite Transmission and Prevention can provide a broader perspective.
Direct Contact with Contaminated Soil or Feces
One of the most frequent ways humans contract worms from dogs is through contact with soil or feces contaminated with parasite eggs or larvae. When an infected dog eliminates, these microscopic eggs or larvae can be present in their stool. If a person, particularly a child playing outdoors, comes into contact with this contaminated soil or feces and subsequently touches their mouth or contaminated food, the parasite can enter their system. This highlights the importance of vigilant cleanup and hand hygiene.
Ingestion of Contaminated Food or Water
Worm eggs or larvae can contaminate water sources or food that has been exposed to infected soil or feces. Consuming food or water that has not been properly prepared or stored, and has come into contact with these contaminants, can lead to human parasitic infections. This underscores the need for careful handling of food and water, especially in environments where dogs with potential parasitic infections may roam.
Common Worms Transmitted from Dogs to Humans
Several types of intestinal parasites that commonly infect dogs can also pose a risk to humans. Each type has unique characteristics and potential health implications. Understanding Understanding Canine Parasites: A Guide to Worms in Dogs can further educate owners on parasite identification.
Roundworms (Toxocara canis)
Roundworms are among the most prevalent worms found in dogs, especially puppies. If ingested by humans, the larval stage of Toxocara canis can cause a condition called visceral larva migrans (VLM). In VLM, the larvae migrate through the human body, potentially damaging organs such as the liver, lungs, eyes, and central nervous system. Ocular larva migrans (OLM), a form of VLM, can lead to vision loss if the larvae migrate to the eye. Early detection and treatment are critical for managing VLM in humans.
Hookworms (Ancylostoma spp. and Uncinaria spp.)
Hookworms are another significant concern for zoonotic transmission. When hookworm larvae from dog feces penetrate human skin, they can cause a condition known as cutaneous larva migrans (CLM). This typically appears as intensely itchy, red, raised tracks on the skin as the larvae migrate. While generally self-limiting and resolving on their own, the itching can be severe and lead to secondary infections from scratching. For a deeper understanding of hookworm transmission, resources on Understanding Zoonotic Hookworms: Transmission, Symptoms, and Prevention are highly informative.
Tapeworms (Dipylidium caninum)
While less common, certain tapeworm species can be transmitted from dogs to humans, most notably Dipylidium caninum. This transmission usually occurs through the accidental ingestion of an infected flea that is carrying tapeworm larvae. Fleas can become infected by consuming tapeworm eggs, and if a dog or human ingests an infected flea, the tapeworm life cycle continues.
Essential Prevention Tips for Pet Owners
Preventing the transmission of worms from dogs to humans involves a multi-faceted approach encompassing hygiene, regular veterinary care, and environmental management. Implementing these strategies significantly reduces the risk for your entire household.

Regular Veterinary Visits and Deworming Schedules
Consistent veterinary check-ups are vital for your dog’s health and for preventing parasite transmission. Veterinarians can perform fecal examinations to detect worm eggs and recommend appropriate deworming treatments tailored to your dog’s age, lifestyle, and the prevalence of parasites in your area. Adhering to a regular deworming schedule, as advised by your vet, is one of the most effective ways to keep your dog free from internal parasites and to minimize the risk to your family.

Maintaining Good Personal Hygiene Practices
Practicing diligent personal hygiene is paramount. Always wash your hands thoroughly with soap and water after:
- Handling your dog, especially before eating or preparing food.
- Cleaning up after your dog, whether indoors or outdoors.
- Gardening or engaging in any outdoor activities where soil contact is likely.
Educating children about the importance of handwashing after playing with pets or outdoors is especially critical.
Ensuring Environmental Cleanliness
Maintaining a clean living environment plays a crucial role in preventing parasite spread. This includes:
- Prompt Disposal of Feces: Clean up dog waste immediately from your yard, local parks, and any other areas your dog frequents.
- Regular Cleaning: Regularly clean your dog’s bedding, toys, and favorite resting spots to eliminate any potential parasite eggs.
- Yard Maintenance: Keep your yard free of debris and ensure proper waste disposal to minimize soil contamination.
Recognizing Symptoms and When to Seek Veterinary Care
If you suspect your dog may have a worm infestation, it’s essential to consult your veterinarian promptly. Common signs of worms in dogs can include visible worms in their stool or vomit, weight loss despite a normal or increased appetite, a dull coat, lethargy, vomiting, diarrhea, or a pot-bellied appearance, particularly in puppies.
For humans, symptoms can vary depending on the type of worm and the extent of the infection. If you experience persistent itching, unexplained rashes, abdominal pain, nausea, changes in bowel habits, or vision disturbances after potential exposure, seek medical advice.
