Hello,
     I know how you are feeling...We were at the vets 4 days ago, and I asked the vet what to do about eating poop. Although my Yorkie doesn't eat poop, my German Shepherd does. She makes me want to throw up when I see her and especially smell her breath. The Worst...
     I asked the vet why???why???does she do that? He said that they might be lacking something in their diet or they just love to eat poop. He said he could give us something for her food to make the poop taste awful. I told him forget it, I tried that already. Also to give them a daily vitamin.
     So that is my poop story.
     Good Luck....I feel for you.
