Nutrition Changes for Senior Dogs

A senior dog's body works differently than it did at two years old — metabolism slows, muscle mass can decline, and existing health conditions start to factor into what "good nutrition" actually means. Diet is one of the most effective tools for supporting a dog through this stage.

Calorie Needs Often Change

Many senior dogs need fewer calories as activity naturally decreases, but that's not universal — some older dogs need more support to maintain muscle mass. Watching body condition, not just the scale number, is the more reliable guide.

Protein Still Matters

A common misconception is that senior dogs need less protein. In most cases, quality protein remains important — even more so, since it helps preserve muscle mass as dogs age. The right amount depends on the individual dog's health status, which is a conversation for your vet rather than a blanket rule.

Watch for Underlying Conditions

Kidney disease, joint issues, and dental changes can all shape what a senior dog should eat — from moisture content to kibble texture. Any diet change for a dog with a known health condition should go through your veterinarian rather than a general senior formula alone.
