Here's a closer look at the most common parasites found in dog poop, how they spread, and what you can do to protect your household.

The Hidden Hazards in Dog Waste

Even if waste breaks down or gets washed away, the parasites and eggs inside it can linger in the soil for weeks or months. That means risk remains long after the pile itself is gone.

Common Parasites Found in Dog Waste

Roundworms

Can spread through soil contaminated by feces

May cause fever, coughing, or abdominal pain in humans

Especially dangerous for children

Hookworms

Eggs hatch in the soil, and larvae can penetrate bare skin

Causes itching, rashes, or more severe infections in pets and people

Whipworms

Found in the intestines of infected dogs

Symptoms include diarrhea and weight loss (primarily affects dogs, not humans)

Giardia

A microscopic parasite spread through contaminated soil or water

Causes diarrhea, cramps, and fatigue in both pets and humans

How Parasites Spread

Parasite eggs are durable—they survive freezing winters, hot summers, and everything in between. They're spread by:

Rain runoff carrying waste into water sources

Kids and pets playing in contaminated soil

Shoes or paws tracking waste particles indoors

Prevention Tips

Scoop waste regularly—daily if possible

Keep up with vet visits and deworming schedules for pets

Designate potty areas away from gardens or play spaces

Practice good hygiene—handwashing after handling pets or outdoor play

Final Thoughts

Parasites in dog waste may be invisible, but the health risks are very real. The best prevention is simple: clean up consistently and keep pets on a healthy care routine.
