Dog Senior Nutrition and Welfare

Nutritional management in older dogs plays a critical role in maintaining quality of life, managing age-related conditions, and supporting healthy ageing.

Key Facts

Dogs are generally considered senior from 7 years, giant breeds from 5 years
Muscle loss (sarcopenia) is common in elderly dogs and worsens mobility
Higher-protein diets help preserve muscle mass in healthy senior dogs
Phosphorus restriction is important in dogs with established kidney disease
Supplements including omega-3 fatty acids may support joint and cognitive health

Welfare Considerations

Appropriate nutrition in senior dogs supports mobility, cognitive function, immune health, and quality of life. Many older dogs are fed the same diet throughout life without adjustment. Regular nutritional assessment as part of senior health checks can significantly improve welfare.

What You Can Do

Schedule senior health checks annually or bi-annually from age 7
Discuss nutritional needs with your vet as dogs age
Consider veterinary nutritionist input for dogs with multiple health conditions
Monitor body weight and muscle condition regularly
Ask your vet about evidence-based supplements for age-related conditions
