We have two dogs, a 50lb Aussie female and a 100lb Black Lab male. The male has always been a poop eater. The female, not so much. Our vet gave us a prescription medicine that seemed to work but was quite expensive, so I ordered several products from Amazon to try. This was the winner by far and the poop eating has largely disappeared (about 95%). It is much more economical and the dogs eat it readily (you sprinkle it on their food). One less annoyance in life!Dave
