Well, the point of the pineapple is to help break down the protiens so the pup is getting the protiens absorbed...lack of protien, in turn, must mean this is why they want to eat their pooh. Perhaps a lack of anything (like potassium as stated above) is the issue.
It can also just be a learned behavior from the mommie dog. If so, your pup will grow out of it.
Perhaps try the banana and maybe some pro-biotics to help with digestion (maybe this will help absorb more of what is lacking).
