Senior Dog Nutrition: Feeding Your Aging Companion

Published: April 4, 2026

Nutritional adjustments and feeding strategies for senior dogs to maintain health.

As dogs age, their nutritional needs change significantly. Senior dogs typically need fewer calories due to decreased activity levels, but they still require high-quality protein to maintain muscle mass. Look for senior-specific dog foods with adjusted calorie content and added joint support ingredients like glucosamine. Older dogs may benefit from smaller, more frequent meals to aid digestion. Consider softer food if dental issues are present. Increase fiber to support digestive health and maintain healthy weight. Omega-3 fatty acids can help with joint health and cognitive function. Monitor water intake as senior dogs are prone to dehydration. Watch for changes in appetite or eating habits, which may indicate health issues. Adjust portions based on activity level and body condition to prevent obesity, which can exacerbate age-related health problems.
