Nutrition for Senior Dogs or Cats
As pets age (typically from 7 years old and up), their nutritional needs change. A proper diet can help support their health, manage chronic conditions, and improve their quality of life.
1. Lower Calories, High-Quality Protein
-
Why: Older pets are less active and more prone to weight gain.
-
But: They still need good protein to maintain muscle mass.
-
Sources: Chicken, fish, egg — highly digestible proteins.

2. Moderate Fat, More Omega-3
-
Reduce overall fat to prevent obesity (if overweight).
-
Add Omega-3 fatty acids (DHA, EPA from fish oil):
-
Helps with joint inflammation
-
Supports brain and heart health
-

3. Digestive Support: Fiber & Probiotics
-
Increase soluble fiber to improve digestion and reduce constipation.
-
Prebiotics and probiotics support gut health and immune system.

4. Joint & Brain Support
-
Glucosamine and Chondroitin: for joint health
-
Fish oil (Omega-3): anti-inflammatory, supports memory
-
Choline and L-carnitine: support cognitive function
5. Managing Chronic Conditions
If your pet has:
-
Kidney disease: low phosphorus, moderate protein
-
Heart disease: reduced sodium
-
Diabetes: consistent fiber and low sugar
→ Ask your vet for therapeutic diets designed for specific conditions.
6. Hydration
-
Always provide clean, fresh water.
-
If your pet has dental issues or doesn’t drink much:
→ Use wet food (canned or homemade) to increase water intake.

7. Small, Frequent Meals
-
Easier on the digestive system
-
Helps regulate blood sugar and energy levels
Recommended Diet Options:
-
Commercial senior pet food: Hill’s Science Diet, Royal Canin, Purina Pro Plan, Wellness, etc.
