Some dogs just eat poop. Try this to get him to stop because its really not good for them in this day and age due to virus. But you can give the pup MEAT TENDERIZER with MSG (Monosodium glutamate) it takes about 72 hours for it to start working.
Per Deb (geisthxe):
You put about a 1 teaspoon on there food each time you feed
- Makes the food taste better (like Chinese food does
- Make stool taste bad when it comes out.
Once the pup stops eating the stool then you can stop until you see it again.
Eating other dog stool you need to just do a correction, have him look at you and sit .. so you distract him from the stool and back to what you are doing.
Also, be very vigilant about cleaning up immediately after to avoid any infections that could be caused from eating the stools.
