works...to a degree
I have been using this product for over a year, and on several of my dogs. I prefer it to other products because of it's seemingly simple and natural ingredients, even though the ingredients are not promoted as natural. It didn't appear to work for my small, senior Boston Terrier rescue who was rather obsessive/compulsive. I think his personality won out over Doc Roy's. For my 8 yr old Brussels Griffon, a sweet boy and also a rescue, the tablets are effective...to a degree. My boy weighs 18 lbs, and the dosage should be 1/2 tab daily, but I have to give him 1 entire tablet daily to stop the bad habit. Still, he picks up the poop and carries it to a nice spot for munching, but just leaves it there without eating--I assume it is because of the taste. He doesn't eat stool as long as I give him one tablet every day, but it doesn't stop his DESIRE to eat it. I guess it is something like alcoholism, or cigarette smoking in that he still wants to eat it. But the bad taste prevents him from doing so. I will continue to purchase the product, because occasionally picking up is not as bad as eating!!
