The only reason I didn’t give it five stars was because I am not sure how well it really worked on its own. I mixed it with bromelain which is a derivative of pineapple that I found in the vitamin store. Bromelain aids digestion. I added it with the forbid. I got the impression that my dog was having problems digesting everything and that’s why her poop seemed so delicious. It says it should work within five days, I didn’t notice it really working until about 10 days. My vet only sold me three of these packages. I like that Amazon was a lot more inexpensive and I got a package of 12 packets. Due to the fact that I had a lot of it I didn’t give up and now my dog has been finally leaving her poop alone. It will make your dog’s poop smell really bad. You will notice that your dog has made an accident in the house, you can’t miss it. It was really important that my dog stopped this bad habit because she was cleaning herself off and she gave herself a urinary tract infection. It was really going to be a nightmare unless I could break her of this. I’m going to keep using my product until I run out. By then I suspect shw will be well over the habit. My dog is a puppy. This seems perfectly fine for puppies. No, I won’t give you a photo of what it does!
