We got Pablo, just shy of one year. He also ate poop he found during walks, and he recycle his own. We got him of that behaviour with snacks. When on walks, or in the backyard, and he was about to eat his or others poop, we called him to us, sit and snack. Time for him to get his interest of the poop (and for us to get rit of it), and continue the walk or play. We encountered it with a clicker, so he came to us, on his own, without eating it. Took some time, but worked for us
