The only way to really stop poop eating is to pick it up as soon as they go.
Neither food you’ve fed is very good. I assume your dogs are seniors and/or need to lose weight. Senior dogs don’t need a senior food; most of them are too low in protein for senior dogs, the exception being Orijen senior.

If they need to lose weight, look at Annamaet Lean or Wellness Core reduced fat. Both may help with the gas; you can try a probiotic as well.
