Hey @pnitzsche , I totally understand your concern. GSDs can be prone to stomach issues, so it’s important to find a diet that works for them. Personally, I’ve had great success with a high-quality lamb or fish-based kibble, as these proteins are often easier on their digestive systems. As for grain-free diets, they can work for some dogs, but I’ve read conflicting opinions on whether grain-free is always the best choice. Some dogs do better with grains like rice or oats because they’re easy to digest and less likely to cause gastrointestinal upset. It might take some trial and error, but I’d recommend starting with a food that has a single source of protein and easily digestible carbs, and see how she reacts to it.
