The predator in your home

Dogs are domesticated wolves, bred to be smaller, more docile and extremely responsive to humans. But they are still predators. The uncontrolled accumulation of dog waste in urban downtown areas is a documented public health issue that goes beyond a mere “quality of life” complaint. Dog feces and urine act as reservoirs for bacteria and parasites. Protecting wildlife from domestic and feral dogs requires a combination of strict enforcement of existing regulations, enhanced community awareness, and the implementation of specific habitat protections. Research indicates that dogs, as common large carnivores, disturb or harm wildlife—particularly shorebirds and small mammals—even when leashed, through predation, chasing, and the presence of their scent, waste, and bacteria. Caring, however, does not mean idolizing. It does not mean putting animals above all else, allowing dangerous behaviors, or prioritizing a dog’s comfort over the safety of others and many people have pet allergies and have to choose themselves daily to survive daily.

How Your Dog’s Droppings May Be Secretly Attracting Rodents To Your Yard and your neighbors as well …

Recent studies have uncovered alarming findings linking dog waste to increased bacterial pollution in urban environments. As cities grapple with waste management challenges, the impact of unattended dog droppings on public health and water quality is coming into sharper focus. Leptospirosis is a serious, zoonotic bacterial disease spreading in cities, transmitted primarily through the urine of infected dogs, rats, and wildlife. It thrives in warm, wet urban environments (puddles, soil) and causes kidney/liver failure in dogs and severe, flu-like illness in humans.

Pet waste primarily consists of feces and urine, which contain bacteria, pathogens, parasites, and nutrients. When not properly managed, these contaminants can enter water bodies and pose risks to human health. “Dogs create about .75 pounds of waste every day, 365 days a year” (Philadelphia Water Department, n.d). According to the EPA, each gram of dog waste can contain 23 million fecal coliform bacteria. “Fecal coliform bacteria are microscopic organisms that live in the intestines of warm-blooded animals. They also live in the waste material or feces, excreted from the intestinal tract” (Water Research Center, n.d). The presence of fecal coliforms in pet waste is significant because it indicates the potential for fecal contamination in the environment. Contaminated water and environments with fecal coliforms pose health risks, as some strains of these bacteria can cause gastrointestinal illnesses if ingestedor if they come into contact with open wounds (Lin et al., 2022). For instance, “diseases and illnesses that can be contracted in water with high fecal coliform counts include typhoid fever, hepatitis, gastroenteritis, dysentery, and ear infections” (Water Research Gate, n.d). Additionally, pet waste left in public spaces can attract flies and other pests, which can carry pathogens and contribute to the spread of diseases. Furthermore, airborne allergens from pet waste, such as dust particles contaminated with fecal matter, can exacerbate allergies and respiratory conditions like asthma in individuals who are sensitive to these allergens. Accumulated pet waste in public areas can also create unpleasant odors, negatively impacting the quality of life for nearby residents and discouraging people from using public spaces for recreation (Mori et al., 2023). Moreover, according to the Water Research Center, pet waste contributes to nonpoint source pollution, which is pollution that does not come from a single, identifiable source. This type of pollution is challenging to regulate and manage.

Many individuals residing in urban downtown areas frequently observe dog owners walking their pets while carrying bags, presenting themselves as responsible citizens. However, they often neglect their duties by allowing their dogs to urinate and defecate on sidewalks behind buildings, subsequently abandoning the waste due to fatigue from carrying the bags. It is evident that not every citizen adheres to proper dog waste disposal practices. Those of us who frequent these urban walking spaces, enjoy visiting farmers’ markets, and appreciate our downtown communities have become increasingly aware of the unpleasant odors emanating from certain buildings where these animals reside. Each time we pass by, we are met with the strong scent of urine, particularly when residents from higher floors, such as the ninth and tenth, take their dogs outside. These dogs frequently urinate and defecate in public spaces, and the waste is not always solid, presenting a significant issue that warrants attention. This situation could potentially lead to a class action lawsuit. We aim to convene a committee of individuals concerned about public health. As someone with a master’s degree in public health and currently pursuing a doctorate in health sciences, I am eager to contribute to making this a priority for 2026. Dog owners wishing to cohabitate in an apartment complex are welcome to do so, as are smokers who wish to congregate and indulge in their habits. However, for those of us who do not own dogs or smoke, we would prefer to reside in environments free from the disturbances caused by those who do.

CLASS ACTION LAWSUIT!!

Citizens can file citizen suits under the Clean Water Act (CWA) against municipalities or entities allowing illegal, untreated discharges of waste, including sewage (which may contain pet waste) into U.S. waters

. These lawsuits require a 60-day notice to the violator and the EPA. The CWA regulates point sources, such as pipes, that discharge pollutants into water without a permit.

* Pet Waste and Runoff: While individual pet waste is generally treated as non-point source pollution, large volumes of pet waste combined with sewage overflows, or “dog piss/waste” contributing to a concentrated point source discharge, can be part of broader illegal, untreated sewage discharges.
