LOL, yes I used Accent with Harry boy when I got him about 5 years ago.. his breeder told me about it..he was fond of his poop ,,
is a learned behavior, doggy moms eat the babies poop to keep the whelping box and area clean, so the babies learn from the moms..
I don't know what is in the Accent that works, I used it with my puppies to make sure they did not eat their poop at 12 weeks when they went home to their families..
just a little sprinkle a couple of times and problem was solved..
