Nutritional needs change as dogs age. Appropriate senior nutrition prevents age-related welfare problems and supports quality of life through the later years.
Senior dog nutrition is a welfare-active area where appropriate feeding directly affects quality of life and disease progression. Dogs with early kidney disease whose phosphorus intake is not restricted progress to renal failure faster, causing preventable welfare harm. Dogs with arthritis who receive anti-inflammatory omega-3 fatty acids have reduced joint pain. Dogs with dental disease unable to chew hard kibble go hungry or swallow unchewed food causing gastrointestinal problems - both welfare harms preventable through appropriate food texture selection. Senior nutrition is not simply 'less of the same' but requires individualized assessment of the specific aging dog's health conditions and how nutrition supports their management.
