Wheat bran needs to be cooked before being fed to dogs. Feeding it in an appropriate amount can relieve dogs' constipation. It also contains a large amount of dietary fiber, which can promote the digestion of fat, and is also rich in vitamin B. But it is best not to overfeed, especially puppies, as it can easily cause gastrointestinal discomfort. It is recommended that owners mix a small amount of wheat bran with some meat and vegetables, such as carrots, chicken breasts, and vegetables, as homemade dog food to ensure balanced nutrition.
