There’s a persistent bit of backyard folklore that dog waste is basically free fertilizer — leave it, it breaks down, the grass wins. Cow manure feeds fields, after all.
The comparison doesn’t hold. Cows eat grass. Dogs eat a protein-heavy diet, and what comes out the other end is acidic enough to burn lawns rather than feed them — those yellow rings around old piles aren’t your grass thriving. More importantly, it’s biologically crowded in a way plant-eater manure isn’t.
What’s actually in it
A single gram of dog waste can contain over 20 million bacteria, including fecal coliform and, commonly, salmonella and giardia. Alongside the bacteria come parasite eggs — roundworm and hookworm especially — which are the part most people underestimate, because the eggs outlast the visible pile by months. The rain flattens what you can see; the eggs stay in the soil, where kids play and where every dog that visits the yard sniffs around.
That’s why the U.S. Environmental Protection Agency classifies pet waste alongside oil runoff and lawn chemicals as a nonpoint source pollutant — the category for contamination that rain picks up and carries into waterways a little at a time, from everywhere at once.
Here, “the waterway” is not an abstraction
The Topsail corridor lives between water. The Intracoastal Waterway and its marshes sit behind the island; the ocean sits in front; the water table under most of our yards is high. When rain moves through a yard in Hampstead or Surf City, it doesn’t travel far before it reaches a ditch, and the ditches don’t travel far before they reach the sound.
The sound is where everyone here fishes, paddles, swims, and lets the dog cool off in July. Bacteria from yard runoff is one of the things that closes shellfish waters after heavy rain. Nobody’s yard does that alone — that’s the nature of nonpoint pollution. Everybody’s yards together absolutely do.
What actually helps
Pick it up, and get it off the property. Frequency matters more than perfection — a yard cleared weekly puts a fraction of the bacteria into the ground that a yard cleared “when it gets bad” does, because the rain isn’t working on a standing supply.
It’s also why we handle disposal the way we do. Poo Patrol doesn’t rake waste into a corner or leave bags in your own bin. We remove it from the property completelyand dispose of it properly, every visit. On this stretch of coast, that’s not a premium extra — it’s just the correct way to do the job.
If your yard has gotten ahead of you, that’s what the one-time cleanupis for — and if you’d rather never think about it again, the first cleanup on any weekly plan is free.
