A recent study revealed that this is the most frustrating behavioural problem that dog owners deal with.
There are lots of theories out there as to why they seem to enjoy this disgusting pastime, but the most widely accepted is that they’re trying to reclaim digested protein.
But let’s not focus so much on why they do it, but what to do about it. It starts with training as a puppy. Accompany your puppy outside always, and pick up stool as soon as your dog defecates. If he shows interest in stool (his or other dogs) give a firm “no!” and redirect his interest to something else, like a toy. As he grows up make sure that your yard stays free of stool. Food additives, such as one called For-Bid, that contain MSG are often successful in making the stool’s taste unappealing.
