Every walk ends with a small bag in your hand. But how much plastic does that actually add up to? And what can you do as a dog owner to avoid unnecessary waste without compromising on hygiene? Here you will find a transparent sample calculation and practical tips.
The calculation: how many bags are used
Around 10 million dogs live in German households, at least one in every fifth household (German pet industry associations IVH and ZZF, market data 2025). On average a dog defecates once or twice a day.
Sample calculation: let us assume two bags are used per dog every day. That gives:
- 10 million dogs × 2 bags × 365 days = around 7.3 billion bags a year
- with an assumed weight of 1.5 to 2 grams per bag, around 11,000 to 14,600 tonnes of plastic
This is a rough upper limit: not every pile is picked up with a bag, for example in your own garden, and the weight depends on size and film thickness. But the order of magnitude shows that conscious use is worthwhile.
What happens to the bags
Used dog poop bags belong in general waste or public bins. In Germany, general waste is mostly incinerated, with energy being recovered. The bags cannot be recycled after use because they are soiled. It becomes a problem when bags end up in nature: plastic does not break down there, and even bags labelled as compostable break down only slowly outdoors.
Is the alternative not to use a bag?
No. Dog poop left behind can contain parasites and pathogens that pollute soil and water and pose a risk to children and other dogs. In almost all municipalities, picking up is also mandatory. So the bag is part of it, what matters is how you use and dispose of it.
How to avoid unnecessary waste
- Use only one bag: one tear-resistant bag is enough. Thin bags that tear or have to be doubled up double the consumption.
- Buy bulk packs: a bulk pack comes with less packaging per bag than many small packs, for example our 1000 dog poop bags for hanging or the 400 bags on 20 rolls.
- Refill your dispenser instead of buying a new one: a dispenser on the leash is simply refilled with new rolls, such as the one in our set of 300 with metal clip.
- Dispose of it correctly: general waste or a public bin, never the organic bin, the recycling bin or the bushes.
- Check advertising claims: "biodegradable" without a certificate and explanation is not a quality feature. Read more in our guide Bio, compostable or recycled?
Frequently asked questions
How many dog poop bags does a dog use per year?
With two bags a day, around 730 bags a year.
Are compostable bags the solution?
Hardly in practice. Dog poop belongs in general waste, so the compostable bag is incinerated too. In nature such bags break down only slowly.
Can I put used bags in the recycling bin?
No. Soiled bags with contents belong in general waste.
