Exactly what they need... *WHAT IS THE DIFFERENCE BETWEEN GRAIN FOOD AND LOW GRAIN FOOD? Grain foods are low in meat, that is, animal protein. The majority of food protein consists of vegetable proteins. The amount of protein written in the food is the total protein amount. The higher the animal protein part of it, the higher the benefit. It is also unlikely to contain allergens. While most food allergies are thought to be against animal protein, they actually occur against another protein in the diet. For example, a dog that has an allergic reaction when eating chicken food may not react to another food containing the same animal protein. The reason for this is the by-products used in the food. In low-grain foods, by-products are selected from non-allergenic foodstuffs, thus trying to prevent the risk of reaction.
