Dogs, our beloved companions, can sometimes carry parasites that can be transmitted to humans. While the thought of contracting worms from your furry friend might be unsettling, understanding the risks and taking preventive measures can significantly reduce the chances of infection. This guide will delve into the types of worms humans can get from dogs, how transmission occurs, symptoms to watch out for, and effective prevention and treatment strategies.
Common Types of Worms Transmissible from Dogs to Humans
Several types of worms can make their way from dogs to humans. The most common culprits include roundworms, hookworms, tapeworms, and whipworms. Let’s explore each type in detail:
Roundworms (Toxocara canis)
Roundworms are intestinal parasites that are particularly prevalent in puppies. Infection in humans, known as toxocariasis, typically occurs when people accidentally ingest roundworm eggs from contaminated soil or dog feces. While adult roundworms reside in the dog’s intestines, the larval stage can migrate to various organs in humans, including the liver, lungs, and eyes.
Hookworms (Ancylostoma caninum)
Hookworms, another intestinal parasite, can infect humans through skin contact with contaminated soil or sand where infected dogs have defecated. Hookworm larvae can penetrate the skin, causing a condition known as cutaneous larva migrans (CLM), characterized by itchy, red tracks under the skin. In rare cases, hookworms can also infect the intestines, leading to anemia and other gastrointestinal problems.
Tapeworms (Dipylidium caninum, Echinococcus granulosus)
Tapeworms are segmented flatworms that live in the intestines of dogs. The most common tapeworm transmitted to humans from dogs is Dipylidium caninum, spread through the ingestion of infected fleas. While generally not life-threatening, Dipylidium caninum infection can cause abdominal discomfort and digestive issues. Echinococcus granulosus is a more serious concern, as it can cause cysts in the liver, lungs, and other organs, requiring surgery or medication. Fortunately, this type is less common in typical household pets.
Whipworms (Trichuris vulpis)
Whipworms are less frequently transmitted to humans but can still pose a risk. Infection occurs through the ingestion of whipworm eggs from contaminated soil. In humans, whipworm infection is usually asymptomatic but can occasionally cause diarrhea and abdominal pain.

How Can You Get Worms from Your Dog?
The primary mode of transmission for most dog worms to humans is through accidental ingestion of parasite eggs or larvae from contaminated environments. This can happen in various ways:
- Contact with contaminated soil or sand: Roundworm, hookworm, and whipworm eggs can persist in the environment for extended periods. Children are particularly at risk due to their tendency to play in the dirt and put their hands in their mouths.
- Poor hygiene practices: Failing to wash hands thoroughly after handling dogs or cleaning up dog waste can facilitate the transmission of parasite eggs.
- Ingestion of infected fleas: Tapeworm infection can occur by accidentally swallowing an infected flea.
- Consumption of undercooked meat: In rare cases, consuming raw or undercooked meat from animals infected with certain types of tapeworms can lead to infection.
Symptoms of Worm Infection in Humans
Symptoms of worm infection in humans can vary depending on the type of worm and the severity of the infection. Some common signs include:
- Abdominal pain and discomfort
- Nausea and vomiting
- Diarrhea
- Loss of appetite
- Weight loss
- Fatigue
- Itchy skin rash (hookworm infection)
- Eye problems (roundworm infection)
Preventing Worm Infections: Protecting Yourself and Your Pet
Preventive measures are crucial in minimizing the risk of worm transmission from dogs to humans. Here are some key strategies:
- Regular deworming of your dog: Consult your veterinarian to establish a deworming schedule appropriate for your dog’s age, breed, and lifestyle.
- Prompt removal and disposal of dog feces: Clean up your dog’s waste immediately and dispose of it properly.
- Regular handwashing: Wash your hands thoroughly with soap and water after handling your dog, cleaning up dog waste, or playing in areas where dogs frequent.
- Prevent flea infestations: Use flea preventatives on your dog to minimize the risk of tapeworm infection.
- Avoid allowing dogs to lick your face: While affectionate, dog saliva can contain parasite eggs or larvae.
- Regularly clean and disinfect your home: Pay particular attention to areas where your dog spends most of its time.
Treatment for Worm Infections in Humans
If you suspect you or a family member has contracted worms from a dog, consult a physician immediately. Diagnosis typically involves stool sample analysis and, in some cases, blood tests. Treatment usually involves antiparasitic medications tailored to the specific type of worm infection.

While direct contact with an infected dog doesn’t directly transmit worms, it increases the risk of exposure to contaminated fur or dander. Regularly washing bedding and practicing good hygiene can minimize this risk.
“Regular deworming is not just about protecting your dog’s health, it’s about protecting the health of your entire family,” says Dr. Emily Carter, a leading veterinary parasitologist at the Animal Health Center. “Prevention is always the best approach.”
“Early detection and treatment of worm infections are crucial,” adds Dr. Michael Davies, a renowned infectious disease specialist. “If you suspect a worm infection, consult your physician promptly. Don’t delay seeking medical attention.”
Conclusion
While the possibility of contracting worms from dogs is a legitimate concern, understanding the routes of transmission, practicing good hygiene, and ensuring your dog receives regular veterinary care can significantly reduce the risk. By taking proactive steps, you can safeguard the health of both yourself and your beloved canine companion. Remember to consult with your veterinarian and physician for personalized advice and guidance.
