Place the dog feces in a compost bin.
Fill the compost bin with sawdust at a ratio of one part sawdust to two parts dog feces. Mix the feces and sawdust using a long utensil such as a stick or wooden spoon. Do not use this utensil for any purpose other than mixing compost.
Allow the compost to cook at a temperature of 140 degrees of higher. Determine the temperature using a long thermometer. The compost pile should automatically reach this temperature if you keep it in an appropriate compost bin.
Compost the mixture for four to eight weeks.
Remove the lid from the compost bin and place the manure along the roots of your non-edible garden plants.
