This is a product I have used over the years. My vet recommended it about 30 years ago when my dog started eating her stool. Works well. However, some dogs you do have to use it more often, depending how long they’ve been doing it. We have a greyhound we just rescued in January of this year, she must have been doing this a long time and not even the foster mom saw her, but I did. So it did take a few months to get her to stop. I also keep the yard cleaned up, but sometimes I just don’t get out there, especially if it rains, so this is a good product. I had a different product and it did not work, so I went back to this. Would definitely reorder.
