As dogs age, their bodies change: metabolism slows, muscle mass declines, joints stiffen and some dogs develop kidney, dental or cognitive changes. The right food can help, but “senior” on a bag is not a regulated standard, so formulas vary widely. Here is how to choose, and which foods are worth a look. We have not fed-tested these foods; picks are based on manufacturer information, veterinary nutrition guidance and owner feedback. Talk to your vet before changing your dog’s diet, especially if they have a health condition.
What older dogs need from their food
- Right calories: many seniors are less active and gain weight easily; extra weight worsens arthritis.
- Enough high-quality protein to help maintain muscle, unless your vet advises otherwise.
- Omega-3 fatty acids (EPA/DHA) for joints, skin and brain health.
- Easy to eat and digest: smaller kibble or wet food for dogs with dental issues.
- A complete and balanced statement (AAFCO) for adult maintenance.
- A brand with veterinary nutritionists on staff, a criterion recommended by WSAVA.

Product information from manufacturers at the time of writing. Formulas change; check the current label.
Kibble, wet or fresh?
- Kibble: affordable and convenient; choose small bites if chewing is hard.
- Wet food: more moisture and aroma, often better for picky or dental-challenged seniors.
- Fresh food: highly palatable and portion-controlled, but more expensive.
How to switch foods
Change gradually over 7 to 10 days, mixing increasing amounts of the new food with the old, to avoid stomach upset. Weigh your dog every few weeks and adjust portions.
