Overview
- Sandra Martínez told La Vanguardia that appropriate nutrition helping maintain healthy weight and muscle mass could extend canine lifespan by about 1.5 to 2 years.
- She criticises popular high-carbohydrate dry foods and recommends species-suited 'natural' options that may be raw or cooked.
- She notes dry food is roughly 10% moisture versus 60–70% in natural diets, warning that low hydration may strain kidneys and contribute to issues such as stones.
- Dogs Trust advises balanced nutrition and suggests commercial diets because homemade or raw feeding can struggle to meet all nutrient needs.
- The RSPCA allows small portions of cooked meats but warns against cooked bones and toxins, and the reports present no new peer-reviewed evidence to verify the lifespan claim.
