Picking up poo in little plastic bags, only to throw them into a larger plastic bag to take to the curb to be collected and deposited in a landfill (my current strategy), vs. one of those in-ground doggie septic tanks which use enzymes to "digest" the waste and distribute it into the ground.
Does anyone have any experience with dog septic tanks, and if so, how much better are they than the plastic bag disposal method? Also, is there a "perfect" place to install it in the lawn; near the vegetable garden, as far from the garden as possible, near a tree, etc.
He's a 60 lb dog, so it's not like I can just let the waste biodegrade!
