We bought this type of food after a suggestion from a friend to try a non grain based food in order to see if it helped with some skin and itching problems she was having. I had never heard of such a thing but my friend has had dogs all throughout her life and she said that many animals as they become older will become sensitive to grains. I tried the food and the dog seemed to enjoy it, so we kept her on it and other non grain treats for about a month. There was a noticeable improvement in both her skin and her coat. I have also noticed a big improvement of her kidney function since the switch to this food. I was really very pleased to know a simple diet change could cause such improvement, for one of my dogs I considered it for all of them. I would highly recommend this dog food to others especially people with an older animal, like ours. I was also surprised to find this food to be comparable in price to almost all the others, and less expensive than a few I have seen.
