After finally reading the ingredients in the dog food recommended by our veterinarian we felt compelled to make a change. Our dog is a female who is 8 years old and has had a weight issue most of her life. The food we were feeding her had corn and grain in it which seemed to only add to her issues. So we found this and gave it a try. She has lost some weight. The smell is really bad though as it has fish in it. All in all though it may have been a life saver for our girl. We have now changed to food for our younger dog to a Wellness brand food as well.
