I got three bottles of this for my Five Springer spaniels after watching the video. It sounded like a good product and may be for some dogs but after using it for a few days my dogs experienced severe diarrhea and gastric upset. So I narrowed it down to the addition of this product once it was discontinued after about a week the diarrhea stopped and they got better. It must just depend on the dogs. Mine have allergies to certain foods so we avoid them User's recommendation: Always pay close attention to your pets and don't assume what works for some will work for yours.
