Why proper segregation and handling of Dog Waste is so important


  • Bacteria and viruses in dog waste can survive for up to 4 years, long after the pile of waste has washed away or “disappeared”.  In fact, testing of average sidewalks where dogs are commonly walked showed extremely high levels of bacteria transferred from the dogs feet and onto human shoes. That is onto the shoes of people that don't even have pets but innocently walk down their neighborhood sidewalk for exercise.

  • One gram of dog waste can contain 23 million fecal coliform bacteria which are known to cause cramps, diarrhea, intestinal illness, serious kidney disorders, blindness and even death in humans

  • Testing has shown that 20-30% if all bacteria in urban watersheds are from dog waste.

  • EPA estimates that two or three days’ worth of droppings from a population of a 100 dogs would contribute enough bacteria to temporarily close a bay, and all watershed areas within 30 kilometres of it, to swimming and fishing

  • Dog feces is 3rd on the list of contributors to contaminated water

  • The Environmental Protection Agency (EPA) classified pet waste as a dangerous pollutant in the same category as toxic chemicals and oil.

  • A single dog will produce more bacteria in one day than a person, a horse and a cow combined. Over a week’s time a single dog will produce the same amount of bacteria as 14 wheelbarrow loads of combined human poop, cow poop and horse poop during the same time.

  • It also can get into the air we breathe: a recent study of air samples in Cleveland, Ohio, and Detroit, Mich., found that 10 to 50 percent of the bacteria came from dog poop.


  • Flushing dog waste down the toilet adds additional strain to our sewage treatment plants which use expensive chemicals and energy to treat human waste and creates additional methane gas.  Flushing creates additional water consumption at a time when we are being asked to conserve our water.


  • Commercial and residential yard composters are not able to achieve the required temperatures to kill pathogens found in Dog Waste


  • Although Dog-Waste accounts for only 4% of total waste volumes (which will now be diverted away from landfill), a main issue within Parks is the contamination of clean recyclable materials through Dog-Waste mistakenly being disposed in a recycling bin.  Once that occurs, all materials within the contaminated recyclable bin will be sent to landfill.  With Dog-Waste now having its own designated receptacle, these recyclables will no longer be contaminated, thus increasing diversion rates within parks to approximately 70%-80% (as most material within Parks are recyclable).
