I have a couple of adult dogs that will do that and it does disgust me. I have tried pretty much everything. With a puppy as young as 9 weeks and I think that's what you say yours is, the first thing is to clean it immediately and don't let him get the chance to go after it. Make sure he does have plenty to eat and after meal time take him to the litter pad or outside so that you know when he poops and if he walks away from it after pooping I would love him up a lot, show him your proud he pooped and proud that he left it alone. Once they are adults if they still have the habit it is very hard to stop it.
One thing that has changed with my crew recently is that we changed everyone to Canidae food. Strangely once we did that, the poop eaters do not seem nearly as interested in the poop.
