can you compost dog poop?
Only in a dedicated pet-waste pile kept away from food crops — dog stool carries roundworm eggs that a lukewarm backyard bin never kills.

which bins can take it?
- hot pile caution
- cold pile no
- worm bin no
- bokashi caution
- tumbler caution
- curbside caution
- hot pile: Only a separate pile you will never spread on edibles — drive the core to 145°F, turn it, and let it cure a full year.
- bokashi: A pet-waste-only bokashi bucket works, but bury the ferment deep under shrubs or lawn, never in a vegetable bed.
- tumbler: Dedicate the drum to pet waste alone; a tumbler you also use for kitchen scraps cross-contaminates food compost.
- curbside: A few programs take pet waste in special carts, but most yard-waste and food-scrap carts ban it outright — check your hauler's list.
why?
Dog stool routinely carries Toxocara canis eggs along with Giardia cysts and Salmonella, and those roundworm eggs stay infective in soil for years once they toughen up. Killing them takes sustained heat: extension pet-waste research uses 145°F held for several days, a temperature a mixed household pile touches briefly at best. Anything cooler leaves live eggs in finished compost.
how to prep it
- Scoop daily while it's fresh rather than letting it weather in the yard
- Mix one part waste with two parts sawdust or shredded dry leaves
- Bury each addition in the pile core and cap it with browns
watch out for
- Finished pet-waste compost goes on lawns, trees, and ornamental beds only — never on vegetables, herbs, or strawberries, no matter how long it cured.
- Site the pile at least 100 feet downhill from wells, streams, and vegetable beds so runoff can't carry pathogens where you eat.
- Pregnant people and anyone immunocompromised should skip handling it and let someone else turn the pile.
often confused with
- Herbivore manure — Cow, horse, and rabbit droppings are prized pile activators; the pathogen problem belongs to meat-eating pets.
quick answers
Can I compost dog poop for my flower beds?
That's the one use extension programs endorse. After a full hot cycle and a year of curing, the compost is fine around trees, shrubs, and lawns — anywhere the harvest doesn't end up on a plate.
Are in-ground dog waste digesters the same as composting?
No. Those septic-style units use enzymes and water to liquefy waste into the subsoil, so nothing is harvested. They need well-drained soil and should sit far from wells, ponds, and any bed you grow food in.
