Teach you dogs to poop............. 😁
OK I'm a wise guy.... But, seriously, I train people how to to train their dogs, so I can chip in..... It's quite possable to teach you dogs to poop in one specific place..
And that place would be somewhere accessable to a garden hose, Its dug out to a good depth, <here in South Africa about 250mm & about 2m diameter & filled with medium size stone crush topped off with smaller aggregate, plant a short stake in the middle for males to lift their legs....and pee
Dog poops, - wash down with water and let the wormy-things under the crush do their stuff ---
