That's a lot of doo doo!

Jefferson County Open Space tweeted a really sh**ty photo this week that caught our attention.

Volunteers from Jeffco spent last weekend on a "tour of doody" at Elk Meadow Dog Park in Jefferson County.

During their tour, they picked up more than 400 pounds of puppy poo!

424 pounds, to be exact.

They tweeted a photo of their volunteers with their crappy collection.

How do they know exactly how much doo they collected? Well, they had a handheld scale with a hook, and hung up each bag to weigh it.

Apparently there was a 'Poolympics leaderboard' for those who picked up the most waste.

Come on, people, clean up after your dogs so these volunteers don't have to!
