How do I deal with dog mess in the garden?

Why daily picking up is the health measure rather than the tidiness measure, correct disposal in the UK bin system, and whether digesters are worth it.

Short answer

Pick up daily rather than weekly, because roundworm eggs take a couple of weeks in the environment to become infectious and daily clearing removes them before that. Bag it and put it in your general waste bin — never the garden or food waste bin, and never down the toilet.

Most people treat this as a tidiness job and do it weekly. The reason to do it daily is a public health one: freshly passed faeces are not the hazard, but eggs left in the soil for a fortnight are, and once they are in the soil they persist for a long time. Daily picking up breaks that cycle almost completely, which is why it is the one habit worth building.

Safety

Dog faeces can carry roundworm eggs which pose a genuine risk to people, particularly children, and those eggs only become infectious after a couple of weeks in the environment — which is exactly why daily picking up matters more than any other measure. Never compost dog waste for use on anything edible, never put it in the garden waste or food waste bin, and always wash hands after clearing up. Keep worming treatment current on your vet's schedule.

What you'll need

A long-handled scoop or grabber
Bags
A dedicated lidded outdoor bin (optional)
Gloves (optional)

Step by step

Pick up every day, at the same time.Attach it to something you already do — first thing with the coffee, or last thing when you shut the shed. Daily clearing removes roundworm eggs before they become infectious and stops the garden becoming unusable, and it takes two minutes.
Use a long-handled scoop and a lidded outside bin.A grabber-and-tray set, or a scoop and a small lidded bin kept by the back door, removes the reasons people put it off. A dedicated outdoor bin with a lid means you are not carrying bags through the house every day.
Bag it and put it in the general waste.In the UK, bagged dog waste goes in the general household waste bin. It must not go in the garden waste bin or the food waste caddy, and biodegradable bags do not change that — they need commercial conditions that a garden waste stream does not provide.
Do not put it down the toilet.It causes blockages and is not what domestic drainage is designed for, and the same applies to cat litter. Some councils publish specific guidance; the default is the general waste bin.
Use the dog waste bins on walks, or any general litter bin.Most councils accept bagged dog waste in ordinary street litter bins as well as the red dog bins. Not picking up in a public place is an offence in most areas with fixed penalties, and it is enforced.
Do not hose it away.Hosing spreads material into the soil and grass rather than removing it, which is exactly the outcome you are trying to avoid. Scoop first, and only then rinse a hard surface if you want to.
Keep worming up to date on the vet's schedule.Regular worming reduces the number of eggs being passed and is the other half of the risk reduction. Your vet sets the interval based on the dog's lifestyle and household — a dog living with young children may be advised to be wormed more often.
Set up a toileting area if the garden is small.Take the dog to one corner on the lead and reward it there, over a couple of weeks. A gravel or bark corner is much easier to keep clean than a whole lawn, and it keeps the rest of the garden usable.
Understand what a waste digester does before buying one.A buried digester with an enzyme powder breaks waste down into liquid that drains into the soil, and it works reasonably in free-draining ground for one or two small dogs. It works badly in clay, slows to a stop in cold weather, and cannot cope with a large dog. Do not site one near a vegetable bed or a water course.
Deal with the lawn damage separately.Urine scorch and mess damage are different problems with different solutions, and the yellow patches are a nitrogen and water issue rather than a hygiene one.

Tips

Buy twice as many bags as you think you need and keep them in three places — the back door, the lead hook and your coat. The reason people do not pick up at home is usually that the bags are indoors.
If a neighbour's dog is fouling your garden, that is a matter for your council's dog warden service, and reporting it is more effective than a note.
Do not use dog waste on a compost heap you will use anywhere near food crops. A separate, dedicated, never-for-edibles heap is the only version of this that is defensible, and most people are better off with the bin.

Common mistakes

Clearing the garden once a week — Roundworm eggs become infectious after a period in the environment, so weekly clearing leaves a window that daily clearing closes. It is a health measure, not a tidiness one.
Putting bagged waste in the garden waste bin — It contaminates a stream that is composted at scale for horticultural use. It goes in the general waste bin regardless of the bag type.
Hosing it into the lawn — It disperses the material rather than removing it, and leaves exactly what you were trying to get rid of in the soil.
Composting dog waste for a vegetable garden — Domestic compost heaps do not reach the temperatures needed to destroy the parasites reliably. It should never go anywhere near edible crops.

If it doesn't work

Grass is patchy and yellow where the dog goes

Cause: Urine, not faeces — Fix: That is a separate problem about nitrogen concentration and watering, and it needs a different approach from clearing up.

Digester has stopped working

Cause: Cold weather, heavy clay, or overloading — Fix: Digesters slow markedly in winter and fail in poorly draining soil. Reduce what goes in, or accept that bagging and binning is more reliable for your garden.

Smell in warm weather

Cause: Waste sitting in a bin in the sun — Fix: Use a lidded bin in shade, empty it into the general waste on collection day, and double-bag in hot weather.

Dog uses the whole lawn

Cause: No designated area — Fix: Lead the dog to one corner and reward it there consistently for a fortnight. Most dogs form a strong preference quickly.

Questions people ask

Which bin does dog poo go in?

The general household waste bin, bagged. Not the garden waste bin, not the food waste caddy, and not down the toilet. On walks, the red dog bins or ordinary street litter bins both work in most areas.

How often should I clear the garden?

Daily. The reason is that roundworm eggs need a period in the environment before they become infectious, so daily clearing removes them in time. Weekly clearing does not achieve the same thing.

Are dog waste digesters any good?

They work reasonably for one or two small dogs in free-draining soil, and poorly in clay or in cold weather. They also should not be sited near vegetable beds or watercourses. For most gardens, bagging and binning is more reliable.
