Older dogs usually need fewer calories and easier digestion, and often benefit from joint support. What they should not lose is protein: cutting it back was old advice, and a healthy older dog still needs good protein to hold muscle. Something has to replace the grain, and it is usually potato, sweet potato, peas or lentils. Those are carbohydrates too. Grain is also a less common trigger than owners expect: animal proteins account for more confirmed food reactions. Read what replaced the grain before assuming an upgrade.
