Quick answer

For a senior dog with sensitive digestion, choose a wet food with a single, easy-to-digest protein source and limited ingredients, such as Denes Senior with Chicken, Lamb and Rice Dog Food, which is also formulated for older dogs' nutritional needs.

Why senior dogs often develop sensitive digestion

As dogs age, their digestive system becomes less efficient. Reduced production of digestive enzymes, slower gut motility, and changes in the gut microbiome can make it harder to process certain ingredients. Common triggers include high-fat foods, artificial additives, and complex protein blends.

Key ingredients to look for (and avoid)

Look for limited, recognizable ingredients: a single novel protein (like chicken or lamb), a simple carbohydrate source (like rice), and no wheat gluten or artificial preservatives. Avoid by-products, excessive fat, and foods with long lists of additives. Wet food is often easier to digest than dry kibble because of its higher moisture content and softer texture.

Diagnosis guide: Is it sensitive digestion or something else?

  • Symptom: Soft stool, occasional vomiting after meals, gas, or reduced appetite that comes and goes. Keep a food diary noting when symptoms occur and what your dog ate.
  • Likely cause: A food ingredient your dog can no longer tolerate, such as a common protein (beef, chicken), grain (corn, wheat), or high-fat content. Switch to a limited-ingredient, single-protein food like Denes Senior with Chicken, Lamb and Rice.
  • Corrective action: Transition slowly over 7–10 days: mix increasing amounts of the new food with the old. Feed smaller, more frequent meals. Ensure fresh water is always available. Monitor stool consistency and energy levels during the transition.
  • When to stop and see a vet: If symptoms persist beyond 2 weeks on the new diet, include blood in stool or vomit, or your dog shows signs of pain (whining, hunched posture). Chronic digestive issues may indicate pancreatitis, inflammatory bowel disease, or other medical conditions requiring professional diagnosis.
