As dogs age, their nutritional needs change. Here's how to choose the best senior dog food to keep your old friend thriving.
What changes with age
Senior dogs often need fewer calories (to prevent weight gain), more support for joints, easier-to-digest ingredients, and sometimes adjustments for kidney or heart health. The right food helps them age comfortably.

Key features to look for
Look for high-quality, moderate protein to maintain muscle, added glucosamine and omega-3s for joints, prebiotic fiber for digestion, and antioxidants for immune support. A recipe formulated for seniors covers most of this.
Support the whole dog
Diet works best alongside other care. Joint supplements like [Cosequin DS Plus MSM](/products/cosequin-ds-plus-msm-joint-supplement) complement senior food, and keeping your dog lean protects aging joints.
Watch weight and appetite
Senior dogs can gain weight as they slow down, or lose it if illness sets in. Monitor both, and see your vet for sudden appetite or weight changes — they can signal underlying conditions.

Frequently asked
- When should I switch to senior dog food?
- Most dogs transition around 7 years old, earlier for large breeds. Ask your vet, who can time it to your dog's health and activity.
- Do senior dogs need less protein?
- Not necessarily — healthy seniors need enough quality protein to maintain muscle. Protein restriction is usually only for specific medical conditions your vet identifies.
