my lil rott pup that i just got eats poo.....he will sit under the others and eat it while its coming out [:'(]i thought he was lacking, so i got him on vitamins.....it hasn't helped, lol.....he's getting fixed here in a couple of weeks, so i'll have the vet do some more bloodwork, but his last series of tests came out good, so i am thinking he's just a poo eater [:'(]i would definately get yours checked out...it's better to rule out everything.....
