Nutritional needs of senior dogs differ from younger adults, with requirements for higher protein, joint support nutrients, and careful calorie management to support healthy ageing.
Optimal nutrition in senior dogs supports welfare by maintaining muscle mass, protecting organ function, reducing joint inflammation, and supporting cognitive health. The common mistake of restricting protein in all senior dogs can cause muscle wasting that compounds mobility problems. Conversely, excess calorie intake in less active senior dogs leads to obesity and its associated welfare harms. Senior dogs benefit from veterinary-guided nutritional assessment that considers body condition, muscle condition, specific health conditions, and individual metabolic needs — rather than automatic transition to a generic senior formula.
