Your yard right now
Two visits a month is the sweet spot for most two-dog households on average-sized lots. The yard stays usable; you skip the worst of the spring backlog.
Your yard health worksheet
Fill in the three inputs, then use the formulas below to estimate waste, bacterial load, and the cleanup cadence we'd recommend for your household.
- Number of dogs in the household: ____
- Weeks since the last full cleanup: ____
- Usable backyard area in square feet: ____
- Waste sitting in the yard (lbs) = dogs × weeks × 7 × 0.5
- Bacterial load (fecal coliform) = lbs × 453.6 × 23,000,000
- Source: 0.5 lb waste per dog per day (EPA / PennState Extension); 23M coliform per gram of waste (EPA NPS pollution literature).
| Your situation | We'd recommend |
|---|---|
| 3+ dogs or yard under 2,500 sqft | Weekly |
| 2 dogs or yard 2,500–6,000 sqft | Bi-weekly |
| 1 dog on a larger lot (6,000+ sqft) | Monthly |
2 dogs · 4 weeks since last cleanup · 5,000 sqft yard = 28 lbs of waste and ~292 billion fecal coliform bacteria. We'd recommend bi-weekly for this household.
Why the numbers matter
The half-pound-per-day figure is the figure most veterinary and extension publications use for an average adult dog. Bigger breeds (German Shepherds, Labs, Goldens) trend closer to 0.75 lb/day; small breeds (Yorkies, Chihuahuas) trend lower. We chose the average because most NJ households have one of the big-three breeds (Lab, Golden, Retriever mix).
The 23 million coliform bacteria per gram figure comes from EPA non-point source pollution literature and is what drives the storm-water rules many NJ municipalities enforce. Dog waste is not fertilizer — it's classified as a pollutant for a reason. In NJ, runoff from yards in the Raritan, Delaware, and Atlantic watersheds carries that load into waterways used for shellfish harvesting and recreation.
The cadence recommendation is calibrated to both the bacterial accumulation curve and the practical "when does the yard become unusable" point our crews see across 3000+ NJ routes. Weekly is the most popular plan for a reason: it keeps the yard ahead of the parasite-egg viability window, and it's short enough that pricing doesn't escalate when you skip a week on vacation.
FAQ
- How accurate is this estimate?
- It's a back-of-envelope number. We use 0.5 lb of waste per dog per day — a common figure from veterinary and EPA literature for an average-sized adult dog. Large breeds run higher (closer to 0.75 lb/day), small breeds lower. The bacterial count uses the EPA's widely-cited 23.0 million fecal coliform per gram of waste.
- Why does scoop frequency matter?
- Waste left on the yard breaks down into the soil and feeds bacteria, parasites, and flies. Roundworm and hookworm eggs can survive in soil for months. Storm runoff carries the bacterial load into waterways — in NJ this means the Raritan, Delaware, and Atlantic estuaries. Frequent removal interrupts all of that.
- What about yard treatments or deodorizing?
- Scooping handles the visible waste; the residue and odor stay in the soil. Our enzyme deodorizer (Simple Green) and Wondercide-based flea/tick/mosquito treatment address the layer underneath. Most households pair weekly cleanup with a monthly yard treatment from March through November.
- I have a fully fenced yard the dog never leaves. Same risk?
- Higher risk, actually. A small enclosed yard concentrates everything — bacterial load per square foot is significantly worse than for a dog that does most of its business on walks. Self-pickup is the cheapest fix; service routes solve the consistency problem when life gets busy.
