  1. 1

    You want to pick an area that is not near roots of trees as they can grow into your compost site. Also, do not dig your compost site near a food garden. Dog faeces contains E. coli, Salmonella, and other bacterial parasites which can contaminate your food. Place your compost site in an ornamental garden area only.

    Dig your compost hole with either a shovel or garden spade. Make it as deep as the length of the plastic garbage bin that you are going to use. You may use a 24-quart bin or even a 30-gallon bin that has a lid, depending on how many dogs you own.

    Drill or cut holes approximately 6 inches in diameter on both sides. Then cut out the whole bottom of your container. This prevents the container from caving in over time and allows effective soil absorption.

    Place your trash container into the hole. Place your lid on the container to make sure that it fits snugly.

    After 48 hours you may begin adding more dog faeces to your compost container on a daily basis.

    Add about a gallon of water once a week and a packet of septic starter once a month to ensure proper breakdown of your dog's faeces. You should not have to empty your container at all.

Tips and warnings

  • Soil absorption depends on the texture of the surrounding soil and also on how many dogs are depositing waste into your compost.
  • Never try to compost cat faeces as this is highly dangerous. Do not place your compost near a water source for humans or animals as this can pollute the water source. It is not recommended to use a metal container as this may rust and contaminate your surrounding soil.
