In clinical practice, the most commonly observed signs include diarrhea, bloating, excessive intestinal fermentation, borborygmi, and periodic loss of appetite. In many cases, the underlying cause is not structural disease but rather the gastrointestinal tract’s reaction to diet composition, ingredient quality, or the lack of an appropriate adaptation period when changing nutrition. **Nutritional management of sensitive digestion** Dietary management is based on reducing digestive and metabolic load. The key factor is high digestibility of ingredients and a simplified diet composition, which allows better control of the animal’s response. An important aspect is also nutrient bioavailability. The degree of processing of raw materials, protein quality, and its structure can influence digestion rate and dietary immunological tolerance. In sensitive animals, highly digestible formulations are preferred, as they do not require excessive enzymatic effort from the gastrointestinal tract. At the same time, supporting the intestinal microbiota is essential, as it plays a key role in stabilizing digestive processes and reducing adverse gastrointestinal reactions. **Food for dogs with a sensitive stomach** In dogs, digestive disorders are most often diet-related and result from food intolerances or nutritional errors such as sudden diet changes or excessive dietary fat content. In nutritional practice, a gradual transition to a new diet is recommended, typically lasting several to over ten days, allowing the intestinal microbiota to adapt to new dietary substrates. Monoprotein diets based on a single, highly digestible animal protein source are generally best tolerated. This approach reduces the amount of undigested residues in the intestinal lumen and limits fermentation processes that may lead to diarrhea and flatulence. **Food for cats with a sensitive digestive system** As obligate carnivores, cats have specific metabolic requirements that directly influence dietary management in cases of digestive sensitivity. Their gastrointestinal tract is adapted to efficiently utilize animal protein but is less tolerant of excess carbohydrates and low-quality plant-based ingredients. Key nutritional considerations include adequate intake of essential amino acids, particularly taurine, as well as high-quality protein sources. Proper hydration is also crucial, especially when feeding dry food, which contains significantly less moisture. **Wet vs dry food – physiological perspective** From a physiological standpoint, both wet and dry food can be used, provided they are properly balanced and suited to the individual tolerance of the animal. Wet food, due to its high moisture content, may support gastrointestinal function and improve stool consistency. Dry food, on the other hand, has a higher energy density and can be well tolerated when formulated with high-quality ingredients. In practice, mixed feeding is increasingly used to tailor the diet to the animal’s individual response. **Criteria for selecting appropriate food** The choice of diet should be based primarily on ingredient quality, digestibility, and bioavailability. Recipe simplicity is also important, as a limited number of ingredients makes it easier to assess the animal’s response and identify potential intolerances. In nutritional practice, there is a growing emphasis on simplified formulations with high digestibility that help minimize gastrointestinal burden and support stable gut function. **Summary** Gastrointestinal sensitivity in dogs and cats requires a physiologically based nutritional approach focused on digestion, ingredient quality, and bioavailability. The key factors include reducing irritants, supporting microbiota stability, and individually adapting the diet to the animal’s response. Formulations designed for sensitive digestion, such as **Belly Welly** diets available at bellywelly.eu, represent an approach aimed at high digestibility and reduced gastrointestinal load.
