01 · The core insight
Most tests are a snapshot. Your dog is a story.
Every test owners buy gives them a single point in time. Your dog at this moment, with this blood draw, with this DNA sequencer. That is useful. It is not enough.
Tests = snapshots
One DNA test tells you what your dog is. One bloodwork panel tells you what is happening today. One methylation result tells you where biological age sits at this exact age. None of them tells you what is changing, what is reversible, and what to do about it now.
Cogua = ongoing
Cogua takes whatever tests you already have (or none) and turns them into a living plan that updates as your dog ages and as new information arrives. Birthday rescore. Post-bloodwork rescore. Quarterly photo and weekly pulse on Access. The plan changes because your dog changes.
This is the part most owners miss. Dogs do not age in a straight line. A protective factor at age six (lean body, daily walks, good dental) might not be enough at age ten. A finding that did not matter at age seven becomes the most important thing at age nine. The plan has to keep up. Tests by themselves do not.
02 · What is actually happening in the field right now
The good news: a lot
Here is a short, honest map of where the science of dog aging is moving. We track these closely. We update the Paw Print methodology as findings mature.
DAP
Dog Aging Project
32,000+ dogs enrolled. NIA-funded. Publishing in Nature, Cell Systems, Mammalian Genome. The most ambitious open-science companion-animal study ever assembled. Their TRIAD trial on rapamycin is generating the first rigorous controlled data on a putative canine lifespan drug. We follow their publications. We integrate findings as they clear peer review.
Loyal
Cellular Longevity / Loyal
FDA-tracked development of the first canine longevity drugs (LOY-002 for older dogs, LOY-001 for large-breed dogs). If approved, these become real therapeutic protective factors that the Paw Print can identify candidate dogs for. We watch the regulatory milestones closely and reflect status accurately in the Paw Print.
Methylation
Epigenetic clocks for dogs
Built on Wang et al. 2020 (Cell Systems) and subsequent work. Direct molecular measurement of biological aging. The science is real. It is also young, with measurement noise that single-test results do not surface. Cogua treats a methylation result as one signal in an evidence stack, never as a verdict.
Multi-omic
Multi-omic and proteomic panels
Emerging research-grade panels measuring multiple biological signals at once - DNA methylation plus proteomics plus metabolomics. Genuinely cutting edge. Currently far too expensive and far too research-grade for most owners. For a small subset of dogs (often very specific high-risk breeds, or owners committed to longevity research), they could be useful. For most, they are still a cool data point.
DNA expansion
Expanded DNA panels (Embark, Wisdom Panel)
Breed identification is mature and very useful. Genetic health markers (at-risk and carrier and clear) are excellent on the conditions they cover. Inbreeding coefficient (COI) is genuinely informative on diversity. The marginal value of repeat DNA testing on the same dog is near zero - it is a one-time test for life.
Wearables
Activity and biometric collars
Activity tracking is well established. Continuous heart rate, sleep quality, and gait monitoring are improving fast. Useful for senior-dog mobility trajectories. Owners who already have a smart collar get value adding that data to a Paw Print. Owners without one do not need to rush out to buy one.
Geroscience
Canine geriatric syndrome framework
Driven by McKenzie, Chen, Gruen, Olby, and others. Reframes canine aging as a multi-system phenomenon that demands multi-system surveillance, not single-marker assessment. This framing is the conceptual spine of how Cogua scores 37 health domains.
03 · Which tests actually move the needle
For most dogs, here is the honest ranking
This is the part owners ask us about constantly. The answer is dog-specific (which is the whole point of getting a Paw Print). But for most dogs, here is roughly how the major tests rank in order of practical impact on lifespan and good years.
Comprehensive bloodwork (annual or biannual)
$80-$250 at most vet practices
CBC, comprehensive chemistry, urinalysis, T4. Helps surface kidney, liver, endocrine, anemia, and inflammation signals that may not be obvious from behavior alone. Often the highest-value baseline before buying advanced tests.
Moves the needle
Dental cleaning under anesthesia (when indicated)
$400-$1,500
Periodontal disease is the most under-recognized driver of poor late-life health. Dental cleanings remove bacterial burden that affects cardiac, renal, and systemic inflammation. Genuinely lifespan-relevant for many dogs.
Moves the needle
DNA breed and health panel (one time, ever)
$130-$200
Embark or Wisdom Panel. One-time test gives you breed percentages, COI, and genetic health markers for hundreds of conditions. Especially valuable for mixed breeds and rescues. After one test, you have it for life.
Moves the needle (once)
Body condition score and weight management
Free (your hands and a scale)
This is not really a test, but it is the single most lifespan-relevant data point you can collect for free, monthly, forever. The Kealy 2002 lifetime feeding study showed ~1.8 years of median lifespan benefit from keeping Labs lean. The lever is in your kitchen.
Moves the needle (free)
Methylation clock for dogs
$130-$300
Direct molecular measurement of biological age. Genuinely informative as one signal among many. Most useful when combined with comprehensive records. Less useful when used in isolation as a verdict. Best for owners already committed to a longevity protocol who want a baseline.
Conditionally useful
Cardiac screening for at-risk breeds
$200-$600 echo plus exam
Cavaliers, Boxers, Dobermans, Great Danes, and other DCM- and MMVD-prone breeds. Catching cardiac change early matters. For dogs without breed risk, skip until your vet recommends.
Conditionally useful
Activity and biometric collar
$130-$300 plus subscription
Useful longitudinal data for senior dogs, mobility tracking, and anomaly detection. If you already have one, integrate the data. If you do not, your dog is not at a disadvantage without one.
Cool, not essential
Multi-omic / proteomic research panels
$500-$2,000+
Cutting edge. Mostly research-grade today. Worth it for owners who are deeply committed to longevity research and who already have the basics (records, bloodwork, DNA, lean body) locked down. For most owners, not yet.
Cool, not essential
Repeating DNA tests on the same dog
$130-$200 per repeat
DNA does not change. One good DNA test gives you the answer for life. Marketing in the industry sometimes implies otherwise. We are telling you straight: skip the repeat.
Skip
Non-specific "wellness" panels marketed direct-to-owner
$80-$400
Some direct-to-consumer wellness tests duplicate what your vet already runs, at higher cost, with less interpretive support. The same money goes further at the vet's office where the panel comes with a professional reading.
Usually skip
Important caveat. These are general rankings for most dogs. Your specific dog (breed, age, history, current findings) might move some tests up or down. A Cavalier needs cardiac screening earlier than most. A Bernedoodle benefits more from cancer screening conversations earlier than most. Specifics matter. That is what the Paw Print Report sorts out for your dog in particular.
04 · How Cogua helps you sort all of this out
You bring whatever you have. We tell you what is worth doing next.
The whole point of the Paw Print is that you do not need to figure out which tests to run before you start. You bring whatever records you already have - vet visits, bloodwork, DNA results if any, photos. We score 37 health domains, surface the three drivers that matter most, and give you three concrete actions. One of those actions is often "this specific test is the one to run next for your dog, here is why, here is the cost range, here is what to ask your vet."
If the answer is "your dog has everything we need to score with strong confidence," we say that. We will not invent a test recommendation to make the report feel more thorough. Diagnostic discipline is one of our four pillars. It is harder to do than it sounds, and we work at it.
Bring all the tests you have, some of them, or none of them.
Every Paw Print starts with whatever records you upload. Limited records produce a Preliminary or Estimated Evidence Confidence score and a clear list of what to add to upgrade it. Complete records produce a Strong Confidence score. We are transparent about which tier you are in.
Saves money, time, and stress.
Owners who get a Paw Print walk into the vet office prepared. They ask better questions. They skip tests they do not need and prioritize the ones they do. The report is also a printable vet-visit script. Less guessing, less throwing money at every panel.
We never make money on the tests we recommend.
Cogua takes zero revenue from supplements, DNA companies, methylation providers, drug developers, or testing labs. We have no incentive to over-recommend. This is the single most important sentence on this page.
05 · What we are watching next
The two-year horizon
Here is what we expect to mature in the near term and how the Paw Print will integrate it.
- First FDA-tracked canine longevity drugs reaching commercial availability. When approved, the Paw Print will surface candidate dogs based on breed, age, current findings, and the prescribing criteria the regulator and the manufacturer publish. We will not promote off-label.
- More accessible methylation clock pricing. Currently several hundred dollars; expected to drop. As cost drops, we expect to integrate methylation as a more routine input rather than a research-grade optional.
- Longitudinal DAP findings on rapamycin and senolytic protocols. The TRIAD trial framework is generating the first rigorous controlled data. Findings will reshape what we consider evidence-based interventions.
- Expanded breed-specific risk literature. Mixed-breed and designer-breed risk modeling is improving. We expect to update breed risk scoring annually.
- Owner-side wearables that integrate cleanly. The data from existing collars is more useful with a clean API. As partners emerge, we will integrate.
