    Carbohydrates for dogs: what to do

    When it comes to animal nutrition, one of the most debated topics is the role of carbohydrates in a dog’s diet and whether they are truly healthy for our four-legged friends.

    We all know that bread, rice, and pasta are very important in the human diet, but is the same true for dogs? 

    In this article, we’ll answer some of the most frequently asked questions on this topic.

    Are carbohydrates really bad for our four-legged friends?

    What are carbohydrates, and which foods are rich in them? 

    Carbohydrates are organic compounds composed of carbon, hydrogen, and oxygen. Found primarily in plant-based foods, they are the main source of energy for living organisms.

    Some of the foods highest in carbohydrates include: 

    • corn, wheat, and barley;
    • pasta and bread;
    • beans and other legumes;
    • fruits and vegetables. 

    Grains are the food group that contains the most carbohydrates.

    Carbohydrates for dogs

    Just as with humans, carbohydrates serve a dual purpose in dogs as well.

    On the one hand, digestible carbohydrates (such as simple sugars and starch) serve as an immediate or stored source of energy. On the other hand, indigestible complex carbohydrates, known as fiber, promote a feeling of fullness and support gut health.

    So what is the difference between humans and dogs? 

    Unlike humans, dogs are naturally carnivorous, but over time they have adapted to a more varied diet. For this reason, although they can digest carbohydrates, these should not be the primary source of energy in their diet, especially if not balanced with high-quality proteins and fats

    Dog Nutrition: Is It Right to Demonize Carbohydrates? 

    Carbohydrates are often (wrongly) demonized in dog diets. 

    How are they used, and in what form do we find them in the body? 

    • They are the body's primary source of energy;
    • (they form liver glycogen, which releases glucose molecules that are used, for example, to provide energy to tissues or to maintain stable blood sugar levels); 
    • make upmuscle glycogen;
    • They are a component of the genetic material in cells.

    How do carbohydrates affect dogs?

    The reason we shouldn’t demonize carbohydrates is that they can be used in a dog’s diet in a “functional” way: by leveraging their nutritional properties, they can support an individual dog’s specific needs.

    Depending on their glycemic index, carbohydrates provide more or less energy

    quickly.

    But what does that mean? 

    We can divide these ingredients into two main groups: high-glycemic and low-glycemic carbohydrates. 

    High-glycemic-index carbohydrates are digested quickly, and the glucose released during digestion is absorbed just as rapidly, causing blood sugar levels to rise. Animals that require readily available energy—such as those with digestive difficulties, convalescents, or some older individuals whose organs are becoming less efficient—will benefit greatly from the immediate availability of glucose. In this way, the dog will not have to resort to converting proteins into sugars for energy, and the proteins can instead be used to maintain the bodily structures in which they are involved. This prevents the animal from developing a protein deficiency.

    In healthy adult animals, the risk of protein deficiency is lower, whereas in animals with medical conditions (or in specific situations), it is important to provide carbohydrates to prevent the body from using protein for energy.

    Low-glycemic-index carbohydrates, on the other hand, are digested more slowly and tend to raise blood glucose levels (blood sugar) more gradually, which then remain more stable over time, promoting a greater sense of fullness in the animal. In a healthy individual, this type of carbohydrate is preferable because it better meets the needs of a carnivore. Furthermore, if the glucose in the blood is not used, it is stored as fat, and the animal runs the risk of becoming overweight or obese. It is therefore easy to see how high-glycemic-index ingredients can contribute to this situation.

    How many carbohydrates should a dog eat? 

    In addition to the type of carbohydrates, it is certainly important to consider the amount present in a product.

    Although dogs have significantly altered their eating habits and digestive capabilities as a result of domestication, they are carnivorous animals and their diet should consist primarily of protein and fat.

    If a dog is unable to digest all the starches in its diet, these starches may be fermented by bacteria in the colon; as a result, the dog may develop diarrhea. From this perspective, it is also essential to consider the cooking method used for these ingredients.

    The Diusapet production process involves subjecting carbohydrate sources to a gentle heat treatment in the presence of steam, which effectively “gelatinizes” (i.e., cooks) the starch, making it highly digestible and thus preventing the problems associated with undercooking.

    What kinds of carbohydrates are suitable for dogs? 

    As we’ve seen, dogs can benefit from carbohydrates. However, it’s important to choose them carefully. 

    So, what are the best carbohydrates for dogs?

    A healthy adult dog or one that is slightly overweight will benefit from low-glycemic-index carbohydrates such as sweet potatoes, pea starch, or brown rice.

    A dog that needs easily digestible ingredients, on the other hand, will benefit from ingredients such as white rice and corn.

    Remember: When choosing dog food, it’s important to opt for a high-quality product that contains a good amount of fat and protein. In addition, it must always include the right amount of minerals and vitamins. 

    Carbohydrates for dogs: yes or no?

    In a dog’s diet, carbohydrates are an excellent source of energy. However, we must always remember that, like all nutrients, they should be evaluated based on the animal’s diet, taking into account the presence of other ingredients.

    It is therefore important to monitor carbohydrate intake and ensure that the dog’s diet is appropriate for its lifestyle, nutritional needs, and age.
