Good luck with that. Spencer was a poop eater on & off his whole life. When he was young, it was constant. All the commercial remedies failed to work. His vet recommended sprinkling the poop with hot sauce & letting him eat it. That didn't work either. I ended up just being a freak about cleaning up. I would follow him & Sadie outside & clean up immediately. As he aged, he did it less & he often would go for long spells without doing it. It didn't seem to make any sense. His vet told me that as gross as it was, it really wasn't dangerous, unless he was eating the poop of strange dogs who might be infected with worms or some other disease.
