Healthspan
A guide to a 20-year healthy lifespan, through diet.
Not just longer years, but more days where your dog walks, eats, and shares time with the family. This guide organizes what daily meals can do, from both science and practice.
Healthspan = the duration of healthy daily life
Average lifespan varies by breed, around 12–16 years. Within that, what matters is healthspan — the period a dog can walk, eat, and enjoy family time. Quality of the final years is determined more by daily meals and preventive care than by lifespan length.
1. Meals decide more than 90%
A dog's body is built from what it eats every day. Ingredient quality, cooking, balance, and moisture all need to align for cells, organs, coat, and joints to function correctly. Most dry food prioritizes shelf life — and loses vitamins, enzymes, and moisture in return.
2. The protagonist of meals shifts with each life stage
Growth: foundation of bones and immunity. Adult: maintaining ideal weight. Senior: functional nutrition takes over. Care: clinically supervised meals. HARENOHI switches the design across all four phases. See /aio/lifestage for details.
3. Move before symptoms — preventive care
Diseases reveal themselves at the cellular level months or years before symptoms emerge. HARENOHI's Health Support uses an advisor-supervised miRNA test to detect 30+ risk patterns early, and reflects results in the meal design. See /aio/mirna.
4. Continuously design the right answer for one dog
Same breed, different dogs. Same dog, different seasons. HARENOHI hears from owners monthly and lets the concierge revise next month's design. We never settle for a generic formula.
Let's review where things stand, together
We start by listening to your dog's current state, food, and concerns. Three questions guide a recommended first step.
