Digestive comfort is an underrated part of visible condition. When a senior dog’s stomach feels settled, you often see it in appetite steadiness, a more relaxed posture after meals, and a coat that looks less dull from inconsistent intake. While this page focuses on appearance-forward care, it’s worth noting that senior diet composition varies widely, and nutrient profiles can differ between brands (German K, 2025).
If you’re considering probiotics, prebiotics, or gentle fiber additions, choose one at a time and keep the rest of the diet stable. Sudden changes can create messy feedback—was it the supplement, the new food, or the new treat? A calm, consistent gut routine supports the kind of everyday polish owners notice: cleaner breath, less gurgling, and a dog who seems more comfortable in their own skin.
If vomiting, persistent diarrhea, or weight loss is present, skip the supplement guessing and call your veterinarian. Supplements are for refinement, not for masking a problem that needs diagnosis.
