Worked fine for my Sable GSD
She is a 60 lb GSD and when I starting giving her 2 of these a day with meals the problem went away immediately. So glad!

I am sorry to say that it did not help at all. Not decrease the order feces or keep my dog from eating it.

Dogs Mega Stool NO More.
We have 3 dogs. 2 females + 1 male. It works great for our male dog. Luckily we don't have a problem with our girls.

Useless...don't waste your $$$
Purchased 4 bottles (for four dogs). One with coprophasia. Used as directed. The results were somewhat surprising. Three of the four dogs began eating each others poop. This stuff just made matters worse. I paid a lot of money to achieve such miserable results. Would not recommend.

Did not work for my bully pup
I followed the directions and instructed by the manager at Petsmart. The first time I found out the horror that she ate poop I googled. The manager had no returns on this product and GNC has a reputable name. My shih tzu is pee and poop on training pad. After giving my pup the GNC for a 3 weeks and not been fast enough to get to the pad when my shih tzu was doing his business she ate it. I was so DISAPPOINTED. I wish to find something that would work.
