Because Schnauzers have very sensitive skin, Royal Canin has developed Miniature Schnauzer 25 which has a patented complex of B vitamins, amino acids, and chelated minerals which reinforces the skin barrier. Essential fatty acids reduces skin inflammation. To keep the schnauzer at their ideal weight, this diet is lower in fat and supplemented with L-Carnitine, which works to burn fat.L-Carnitine also reduces the amount of fat in the blood stream. Nutrition optimizes the body's ability to manufacture melanin, the pigment responsible for the coloration of skin & coat. Miniature Schnauzer 25 enhances the schnauzer's natural color. Because of specialized kibble & sodium tripolyphospate Miniature Schnauzer 25 reduces dental plaque & limits tarter formation.

It is possible, I suppose, that RC Miniature Schnauzer food may not be the right food for your dog, even though it is recommended for MS. Buster was put on RC Sensitive tummies, but when we found out the high protein level we took him off it. As I said earlier, he is happy on Winalot and Chappie. Perhaps it is trial and error to find the food that suits your dog best of all. Good luck and let us know how you get on.
