Carbohydrates are a necessary source of glucose, which is important for cellular health. If the dog’s diet does not contain an adequate amount, the liver must work overtime to compensate, using proteins to make glucose. Carbohydrates are found primarily in plants such as grains like wheat, corn and cereals, flour and potatoes. A balanced diet should contain about 50% in dry weight of carbohydrates, and of that, only half should be cereals.
To aid digestion, all types of carbohydrates need to be boiled, baked or toasted before feeding to a dog. Starches from oats, corn and potatoes in particular are difficult to digest unless cooked. On the other hand, white and whole-wheat bread are two of the best natural foods to include.
