Hey There,
Following is the product that you need to use for "poop-eating"

i heard from many people is that this product works 100%. My baby boy never ate his poop so I cannot give my personal opinion.
I do use belly bands with Roscoe and it appears to be working fine...Actually, he never pees in it for some reason so kind of learnt how to hold (until I put him into his xpen)...I got it from a YTer: Tiger's Mom...You send her the measurements of your dog and she ships the belly bands for you...You do use a feminine hygine pad (like always) along with it...
Hope this helps!
