Sorry about the poo issue..I guess redirecting her with a treat and telling her a firm no when she goes to eat her poop would be the best method. Ive also read on here sometimes it means they have some deficenecy in their diet that makes them eat it. What do you feed your puppy? They have some really knowledgeable people on here.
As to not going. I used a teaspoon of real canned (no sugar added pumpkin) worked like a charm. I got that on here too!!!
