Can You Compost Dog Poo Safely? What You Need to Know Before You Start

By Dr Duncan Houston

Quick Answer

You can compost dog poo safely, but only if it is done correctly with high heat, proper setup, and strict handling. Most home compost systems do not reach the temperatures needed to kill parasites and bacteria, so for many owners, composting is not practical or safe.

As a veterinarian, I like the idea of reducing waste. But I also see the risks when composting is done incorrectly. This is one of those areas where good intentions need to be backed by proper method.

Should You Compost Dog Poo at All?

Composting dog waste can:

• Reduce landfill waste

• Lower methane emissions

• Turn waste into usable material for non-edible plants

But it is not as simple as composting food scraps.

Dog waste contains:

• Parasites

• Bacteria

• Potential drug residues

So it requires a completely different level of care.

The Biggest Risk: Parasites and Pathogens

Dog poo can contain:

• Toxocara canis (roundworm eggs)

• Giardia

• Salmonella

• E. coli

These can:

• Infect humans

• Contaminate soil

• Affect wildlife

This is why composting dog waste is not recommended unless done properly.

What Safe Composting Actually Requires

To compost dog poo safely, you need:

High heat

• At least 60°C consistently

• This is required to kill parasites and bacteria

Correct balance

• Nitrogen (dog waste)

• Carbon (sawdust, dry leaves)

A typical mix:

• 2 parts dog waste

• 1 part carbon material

Proper management

• Turn the compost regularly

• Monitor temperature

• Keep moisture balanced

• Use a closed or insulated system

This is an active process, not a “set and forget” bin.

Where You Can Use Dog Poo Compost

Even when done correctly:

• Use only on ornamental plants

• Do not use on vegetables, herbs, or fruit

• Keep away from areas used by children

This is a safety requirement, not a suggestion.

When You Should NOT Compost Dog Poo

Avoid composting if your dog:

• Is fed a raw diet with high pathogen risk

• Is on medications that may pass into waste

• Has parasites or illness

• Produces inconsistent or abnormal stool

Also avoid composting if you:

• Cannot maintain temperature

• Do not have the right setup

• Cannot manage the process consistently

In these cases, safer disposal is better.

Compostable Bags: Do They Help?

Not necessarily.

Many compostable bags:

• Require specific conditions to break down

• Contain plastic-like materials

• Do not degrade properly in home compost

If used:

• Choose certified home-compostable bags

• Ensure your compost system is suitable

Otherwise, they may just sit in the compost.

A Simple Reality Check

Ask yourself:

• Do I have space for a dedicated compost system?

• Can I monitor and manage it properly?

• Am I comfortable handling dog waste this way?

If not, composting is probably not the right option.

Better Alternatives for Most Owners

For most people, safer and more practical options include:

Reusing materials

• Bread bags

• Food packaging

This reduces new production.

Using recycled poo bags

Recycled bags:

• Reuse existing plastic

• Reduce environmental impact

• Work with current waste systems

This is often the most realistic eco option.

Reducing usage

• Use fewer bags where possible

• Avoid unnecessary waste

Small changes add up.

Common Mistakes

• Mixing dog waste with food compost

• Not reaching safe temperatures

• Using compost on edible plants

• Assuming compostable bags solve everything

• Underestimating health risks

These mistakes can turn a good idea into a real problem.

Is Composting Right for You?

Composting dog poo may suit you if:

• You have space

• You can manage it properly

• You understand the risks

For many owners, it is not practical.

And that is completely fine.

Final Thoughts

Composting dog poo can be done safely, but it is not easy or low-maintenance.

For most dog owners:

• It is safer to use proper waste disposal

• Recycled or reused materials are more practical

• The focus should be on realistic, consistent choices

The goal is not perfection. It is making better decisions that work in real life.
