A BARF diet (Biological Species Appropriate Raw Feeding) can help with gastrointestinal problems, as it allows the dog's diet to be individually adapted to its needs. Such a diet can be particularly useful in cases of food intolerance, allergic reactions or other diseases of the digestive system. However, it is important that a BARF diet is carried out under professional guidance, as it can be difficult to dose all nutrients in the right proportions. In addition, when changing to a BARF diet, the dog should be accustomed to the new diet slowly and carefully to avoid gastrointestinal problems.
