Leave it to a Facebook neighborhood group in town to ask the big questions. And this week’s query is this: “Is it safe to flush your dog’s poop down the toilet?”

The answer is yes, if it’s not in a bag.

“Never flush plastic bags or any kind of plastic down the toilet. The same goes for ‘flushable’ wipes and disinfecting wipes,” says Milwaukee Metropolitan Sewerage District spokesperson Bill Graffin. The bags and wipes can cause problems not only for sewer systems, but also for the plumbing in your house.

The Environmental Protection Agency endorses flushing as a safe way to dispose of dog feces.
