How to Compost Dog Waste Safely

Let’s face it—picking up dog poop is a part of the deal when you own a pup. But have you ever stopped to think about where all that waste goes? Millions of pounds of dog waste end up in landfills each year, often wrapped in plastic bags that can take centuries to decompose. Fortunately, there’s a sustainable solution that more and more green-minded pet parents are turning to: composting dog waste.

When done properly, composting dog waste is safe, environmentally friendly, and incredibly rewarding. Here’s how to do it right.

Why Compost Dog Waste?

Dog waste is often seen as a “hazardous material” due to pathogens like E. coli and Salmonella. But with the right method, those pathogens can be safely broken down in a hot composting system or separate digester. Benefits of composting include:

• Reduces landfill waste

• Less plastic bag use

• Creates usable compost (in some cases)

• Saves money on waste disposal products

Is It Safe to Compost Dog Waste?

Yes—IF done properly.
The key is understanding the difference between:

• Regular composting (for food/garden waste)

• Dog waste composting (requires higher heat and specific management)

Dog waste compost should never be used on edible plants. It’s best suited for:

• Decorative gardens

• Lawns

• Trees and shrubs

This keeps any residual pathogens away from humans and food sources.

How to Start Composting Dog Waste

1. Choose the Right Method

There are two primary options for composting dog poop:

️ DIY Dog Waste Compost Bin

This is similar to a backyard composter but designed for waste only.

How to build:

• Use a plastic garbage can or bucket with a lid.

• Drill holes in the sides and bottom.

• Dig a hole in your yard and place the bin inside it (lid above ground).

• Add gravel or soil at the bottom for drainage.

• Start adding dog waste, and layer with sawdust or leaves.

Key Tips:

• Add septic starter or enzymes to break down waste.

• Keep it moist but not soggy.

• Stir occasionally for aeration.

• Let it “cook” for 6–12 months before using the compost.

Enclosed Digester System

These systems are designed specifically for pet waste and use enzymes, bacteria, or heat to break it down. Brands like Doggie Dooley offer pet waste digesters you can bury in your yard.

Pros:

• Easy to set up

• Minimal smell

• Safe and self-contained

Cons:

• Works best in warmer climates

• Not suitable for clay or compacted soils

2. Use Biodegradable Bags

If you use poop bags, make sure they’re:

• Certified compostable

• Made from cornstarch or plant-based materials

• NOT greenwashed (some “biodegradable” bags break down into microplastics)

Some great options: BioBag, Pooch Paper, Earth Rated Compostable Bags

3. Maintain Proper Temperature

Dog waste must reach at least 140°F (60°C) to safely kill pathogens. A standard garden compost bin rarely reaches this temperature without careful management.

Use a compost thermometer to monitor. Turning the pile and adding nitrogen-rich materials (like grass clippings) can help boost heat.

4. Know What NOT to Add

❌ Cat litter (unless labeled compostable and safe)
❌ Trash or plastic
❌ Food waste (in a pet-only bin)
❌ Edible plant trimmings (keep compost for ornamental plants only)

Alternatives to Composting

If composting isn’t an option for you, try:

• Flushable poop bags (check with your municipal system first)

• Municipal pet waste collection services (in select areas)

• Burying in a safe, isolated garden bed (not ideal, but better than plastic bags)

Common Myths About Dog Waste Composting

❌ Myth: Dog poop is just like cow manure.
Not true. Cows are herbivores—dogs are omnivores and their waste contains more pathogens.

❌ Myth: All compost is safe to use.
Compost made with dog waste must never be used on vegetables or herbs.

❌ Myth: It’s too complicated.
Once you set up a system and learn the basics, it becomes as easy as tossing the waste in and giving it a stir every so often.

Final Thoughts

Composting dog waste might seem like an unusual idea at first—but it’s one of the most impactful ways to reduce your pet’s environmental pawprint. With the right setup and care, you can safely divert waste from landfills, minimize plastic bag use, and even create useful compost for your non-edible plants.

It’s a small change that makes a big difference—and your dog will never know the difference between landfill and compost. But the planet will.
