Dog Age & Care 🔧 Dog Age Calculator (UCSD DNA Epigenetic Science)

Slowed, not stopped — and only through unglamorous fundamentals. Nothing resets the methylation clock, but leanness, exercise, dental care, and preventive medicine measurably bend its curve. Every validated lever is boring; every exciting claim lacks canine data.

What actually moves the clock

Lean lifetime weight: the only intervention with randomized lifespan data (+~2 years).
Consistent exercise: muscle, joints, cognition.
Dental care: removes a chronic inflammation source.
Preventive vet care: vaccines, parasites, early disease detection.

What to skip

Anti-aging supplements, unproven injections, and biohacker protocols marketed from human trends: no canine longevity trials support them, and some carry real risk. Spend that budget on weight management and vet visits — then watch the dog age calculator reminding you which stage you are protecting.

Questions & answers

Do longevity supplements work for dogs?

None has randomized lifespan evidence in dogs. Omega-3s help joints; the rest is marketing ahead of data.

Can aging be reversed?

No intervention reverses canine aging. The achievable goal is a slower trajectory and compressed morbidity.

What is the single best action?

Keep the dog lean for life. It beats every other lever on evidence quality and effect size.
