Rice - white in dog food
Rice comes in many forms, from long grain and basmati varieties to shorter forms like pearl rice and short-grain rice. The nutritional characteristics of most forms of rice is very similar, and most varieties can be found in both their whole, brown form and their polished, white form.
White rice is simply brown rice that has been milled and polished to remove outer bran, germ and aleurone layers. Unfortunately, these layers contain the vast majority of the grain's nutrients and once removed the remaining white rice is almost entirely starch.
On ingredient lists, white rice is often listed simply as 'rice'. In general, unless it specifically says that the rice is brown or whole grain, it is usually safe to assume the rice being used is white.
