The only thing that worked for my dogs that had developed this nasty habit was to follow them around, when they had a bowel movement, scoop/discard immediately.
Out of sight, out of mind. After a while they stop turning around to look for it, lol.
Also, if you are feeding 1 or 2 measured meals per day, you will learn the dog’s pattern and will be able to predict when he will have a bowel movement and avoid surprise eliminations.
In other words don’t free feed, and don’t give them the opportunity to be alone with their feces. Some dogs outgrow it, but often it is something you will always have to keep a eye on.
I have never tried any supplements for coprophagia, the price deterred me and the fact that they look like chemical junk? Also, you would have to give them to every dog in your household, plus I have heard that they don’t work.
PS: Has the vet ruled out medical issues? Good article here : http://www.aspca.org/pet-care/virtual-pet-behaviorist/dog-behavior/coprophagia-eating-feces (excerpt below)
Medical Problems to Rule Out
Starvation, Malnutrition or Malabsorption Disorders
If your dog isnāt getting sufficient food or isnāt able to digest the nutrition in his food, he may resort to coprophagia as a way to supplement his diet. Before doing anything else, itās important to have your dog thoroughly examined by a veterinarian to rule out medical problems that could cause coprophagia.
