This will chemically scorch the entire alimentary tract of your dog. You may have to treat with pro-biotic supplements for months after to cure the diarrhea . It will kill off healthy bacteria colonies necessary for normal digestion. Nutrition can not be derrived from food without bacteria colonies. I worked at a Vet Clinic when this first came out. If your pet has tape worms treat specifically for that alone. There are other wormers that are not as harsh on the dogs system. I accidently ingested a tiny amount of this. I cut the dose in half on a wooden chopping block and the next day residue still there got into food that I made for myself. This was like having labor pains all through my stomach and bowels for 2 days. After experiencing this- I threw the rest out.
