Intervention library

What helps. What might. What’s still being tested.

Explore the ideas that could help your dog live better. Each research guide starts with Nara’s take, explains how the intervention may work, and connects the evidence to practical decisions.

Evidence, safety, relevance, and action are different questions.
MethodologyFive questions, never one scoreSee how Nara separates biological promise from demonstrated benefit.
Evidence maturity
How far the research has actually progressed for a specific claim.
Evidence directness
Whether the evidence is in dogs, in another species, or mechanistic only.
Safety certainty
How well the risk profile is characterized — separately from efficacy.
Personalized relevance
Whether it applies to this dog, right now, given the profile we hold.
Actionability
Who should be making the decision, and in what setting.
Research guides and evidence assessments
Every entry has an owner-facing guide with linked sources. Its separate evidence assessment records the accepted claim, confidence, limitations, and safety context. A new article does not automatically mean stronger evidence.

For your dog

01

Foundations

The boring interventions may still matter most. These have the strongest and most direct canine support, and they are owner-directed.

Foundations

Healthy body condition

What canine lifespan research tells us about body fat, muscle and feeding—and why lighter is not always healthier.

Optimization

Reasonable additions once the foundations are in place, usually for a defined purpose rather than for everything.

Optimization

Omega-3 EPA and DHA

The strongest canine evidence is for particular clinical uses, especially osteoarthritis—not a general promise of longer life.

Creatine

Dogs can absorb supplemental creatine. Whether it reliably improves strength, muscle or healthy ageing is a different question.

Why low taurine can matter in some dogs, and why correcting deficiency is different from supplementing every healthy dog for longevity.

Glucosamine, marine lipids and collagen do not share one evidence base. Compare the formulation and the outcome, not just the joint-health label.

Sleep and recovery

Sleep supports normal function, but disrupted rest can also reveal pain or cognitive change. Here is what the dog research can tell us.

Emerging

Early evidence is not proof. It is not nothing, either. These are worth understanding and, in some cases, worth following closely.

04

Experimental and investigational

Scientifically serious, not ready for routine owner-directed use. Listed here so you can understand them — not because Nara recommends them.

Experimental and investigational

Senolytics

A senior-dog combination trial offers an interesting cognitive signal—but it does not prove that senescent-cell clearance extends canine healthspan.
