Leaving Pet Poop on the Sidewalk Isn’t Only Bad Manners—It’s Hazardous

Have you ever been out on a walk and as you take that next step, you feel the slippery squish of poop under your foot?

The Dangers of Neglected Pet Waste

It’s not just gross. Beyond the mess and the smell, it’s potentially infectious. That’s why signs reminding pet owners to “curb your dog” and scoop their poop have been joined in some places by posted warnings that pet waste can spread disease.

Zoonotic Hazards: A Veterinarian’s Perspective

As a small-animal primary care veterinarian, I deal with the diseases of dog and cat poop on a daily basis. Feces represent potential zoonotic hazards, meaning they can transmit disease from the animals to people.

The Scope of the Issue

The reality is that waste left to wash into the soil, whether in a neighborhood, trail, or dog park, can spread life-threatening parasites not just among dogs and cats, but also to wild animals and people of all ages. A 2020 study found intestinal parasites in 85% of off-leash dog parks across the United States.

Human Health Impacts

While human diseases caused by soil-transmitted parasites are indeed considered uncommon in the United States, it’s crucial to recognize the global scale of this issue. These parasites have a far-reaching impact, infecting as many as an estimated billion people worldwide. This staggering statistic underscores the significance of responsible pet waste management beyond merely maintaining cleanliness in public spaces.

When we see signs reminding us to pick up after our pets, it’s easy to dismiss them as mere reminders for good manners. However, they carry a deeper message – one that urges us to actively participate in safeguarding our community’s health. By promptly and properly disposing of pet waste, we are not only preventing unsightly messes but also mitigating the risk of transmitting harmful parasites and diseases.

Each time we heed these reminders and scoop our pet’s poop, we contribute to a cleaner environment and reduce the likelihood of contamination that could harm both humans and animals. It’s a small yet significant action that collectively makes a substantial difference in protecting public health.

Therefore, the next time you encounter a sign prompting you to pick up after your pet, remember that it’s more than just a request for cleanliness – it’s a call to action to prioritize the well-being of your community. Together, through responsible pet waste management practices, we can create safer and healthier environments for everyone.

Understanding the Risks

Common dog poop parasites include hookworms, roundworms, coccidia, and whipworms. Hookworms and roundworms can thrive in a variety of species, including humans.

Impacts on People and Pets


The susceptibility of dogs and cats to parasitic infections mirrors the risks faced by humans. Beyond the well-known threats of hookworms and roundworms, our beloved pets are vulnerable to a range of other parasites, including whipworm, giardia, and coccidia. These parasites can cause debilitating symptoms in animals, mirroring those experienced by humans afflicted with similar infections.

However, the dangers don’t stop there. Unattended pet waste poses additional risks beyond parasitic contamination. It can also harbor canine or feline viruses such as parvovirus, distemper virus, and canine coronavirus. These viral infections have the potential to induce life-threatening diseases in other dogs and cats, particularly in those that are unvaccinated or in vulnerable populations such as puppies and kittens.

The implications of these risks extend beyond individual pets to the wider community. The spread of these diseases can have devastating consequences, not only for affected animals but also for the pet owners and caregivers who may inadvertently come into contact with contaminated environments.

Therefore, it is imperative for pet owners to remain vigilant in managing their pets’ waste and to prioritize regular veterinary care, including vaccinations and preventive measures against parasites. By doing so, we can help protect not only the health and well-being of our beloved animal companions but also the safety of our communities as a whole.

Responsible Management Practices

So, wherever your dog or cat relieves himself – at the park, in the woods, on the sidewalk, or even in your yard – pick up that poop but always avoid contact with your skin.

Minimizing the Impact

By keeping your pets on regular parasite prevention protocols, with annual testing for intestinal parasites and routine removal of fecal material from the environment, you can help to minimize the potential for these diseases among all the mammals in your environment – human, pet, and wild.

Key Points to Remember

  • Pick waste up and safely throw it out regardless of where your pet poops. Sanitize your hands afterward.
  • Wash your hands before eating or touching your face while gardening or working in the yard.
  • Avoid rinsing poop into the soil. Using rain or a garden hose only removes the visible mess, not the microscopic issues.
  • Make sure sandboxes are covered when not in use.
  • Keep your pets on monthly intestinal parasite deworming schedules.
  • Have your vet test your pet’s poop annually for intestinal parasites.

Conclusion: Preserving Health and Ecosystems

By recognizing the dangers associated with neglected pet waste and embracing responsible management practices, we not only safeguard human health but also protect the integrity of the broader ecosystem. Our actions extend beyond mere cleanliness; they play a vital role in preserving the delicate balance of our environment.

By diligently picking up after our pets, we actively prevent the spread of parasites and viruses that pose a threat to both humans and wildlife. This conscientious effort minimizes the risk of contamination in public spaces, ensuring that our communities remain safe and healthy environments for all inhabitants.

Through consistent vigilance and a commitment to proper waste disposal, we demonstrate our dedication to upholding cleanliness standards and promoting public health. Additionally, regular veterinary care for our pets helps identify and address any potential health issues, further contributing to the well-being of our furry companions and the surrounding ecosystem.

In essence, by taking proactive steps to manage pet waste responsibly, we demonstrate our respect for our environment and its inhabitants. Each small action, whether it’s picking up a pile of poop or scheduling a veterinary check-up, collectively contributes to the preservation of our communities and the natural world. Together, through our collective efforts, we can ensure a cleaner, healthier future for generations to come.
