Your dog earned better
than what the market built.
Your dog gives you their entire life. No negotiations. No conditions. Just devotion, from the first morning to the last. They do not calculate what they are worth to you. They just show up, every single day, and give you everything they have.
Unfortunately, the systems built around that love were mostly designed to profit from it.
The DNA testing industry charges you $200 and locks your dog's genome in a corporate vault you will never access. The pet food industry spends more on marketing than on nutrition research and fills every recommendation layer with affiliate commissions. The veterinary information landscape is sponsored by the brands it is supposed to evaluate. The advice you find at midnight when your dog is sick and you are scared is written to sell, not to inform.
Most systems that touch your dog's life were built to monetize the devotion you feel for them. Your love is the product. Your panic is the funnel. Your grief is the upsell.
We think that is backwards.
Sniff exists because your dog earned better than what the market built. The science about dogs should be free. The data from your dog should belong to you. And when your dog's life teaches us something, that knowledge should help every dog that comes after, not sit in a database that gets sold off in a bankruptcy.
What happens when you add your dog
Your dog gets placed in a genetic universe alongside 14,478 research dogs from real scientific studies across 342 breeds. Their position is computed from actual genetics; not a label, not a guess, not a marketing category. It is a permanent coordinate in a 256-dimensional space that captures how your dog relates to every other dog in the atlas.
You see who your dog's nearest genetic neighbors are. You see what traits your dog likely carries based on real loci. You see which breeds your dog clusters with and which ones they are furthest from. You get a page for your dog at a permanent URL you can share, show your vet, or send to anyone who wants to see who your dog really is.
This is your dog's page. You own it. You share it. You decide what is on it. It is not a report locked behind a login. It is a living profile in a public atlas that gets smarter over time.
All of it is free. All of it is yours.
Every dog starts as a Charted star
When you add your dog, you tell us what you know: their breed or breed mix, their size, their coat, their health history. We use that information to estimate their genetic position and place them in the atlas among the research dogs.
A Charted star is real. It is computed. It is placed with care. It is a calibrated estimate based on the genetic profiles of thousands of dogs with known ancestry. Your dog gets a neighborhood, trait predictions, nearest genetic neighbors, and a contribution statement explaining how their presence helps the atlas.
Charted dogs help the atlas in ways most people do not expect. Every dog that enters adds signal. Every breed mix we have never seen before teaches the system something about how those breeds combine. Every health condition reported in the intake flow adds a data point to the health patterns emerging in that genetic neighborhood. Even without DNA, your dog is contributing to science.
Charted stars are incredibly important for multiple reasons. If you agree to update and share, you can provide important details such as the food they eat, what the vet says about them, what their personality is like. These short surveys that you can take as little as once a year give the atlas a very necessary wealth of information.
Sequenced stars see further
If you have a DNA test file from Embark, you can upload it and your dog becomes a Sequenced star. Their position is computed from their actual measured genotype, tens of thousands of real genetic markers placing them precisely among the research dogs. The confidence is higher. The trait calls are sharper. The neighborhood assignment is more exact.
Soon, Sniff Panel will let you sequence your dog's whole genome for less than what existing tests charge for a fraction of the data. Your dog gets a complete genome in standard formats you own and keep forever. Not a report. Not a PDF. The actual genome files that any researcher, any vet, any tool can read. That genome improves over time as the reference panel grows. Your dog's results get more precise without you doing anything, because the system around them got smarter.
A Sequenced dog is the most valuable contributor to the atlas. Their genotype anchors the neighborhoods. Their alleles refine the trait frequencies. Their data sharpens the health patterns for every dog near them. And when a researcher needs dogs like yours for a study, a Sequenced dog surfaces first.
All of this will always be free. Uploading your dog's DNA test is a valuable piece of information that helps us understand more about your dog, and also makes the atlas smarter, which serves every dog and dog owner on the planet.
But every Sequenced star started as a Charted star. The door is the same for everyone. The depth comes when you are ready.
This started with a dog named Pax
Pax was a Rottweiler-Husky mix who lived for 11 years and changed everything about how I think about dogs and data. Before he died in March 2026, I submitted his DNA to a testing company. I got back a report. Breed percentages. A few health markers. A login page.
When he passed, I wanted his raw genetic data. The actual genome. The file that a researcher or a vet or a future tool could use to learn something from his life. The company said no. The data was theirs.
Pax will always be a Charted star in this atlas. Not because we chose that for him, but because the company that holds his genome will not release it. The raw data that would make him a Sequenced star is locked behind a policy I cannot change.
I firmly believe that data belongs to the people who feed and care for their dog every single day. Not a corporation. Sniff exists to make sure no owner ever has to accept that answer again.
Why every dog matters
The purebred dogs in the atlas are essential. They are the landmarks. They define the breed clusters and anchor the coordinate system. Without them, there is no map.
But the dogs between the clusters, the mixes, the rescues, the mutts, the dogs nobody planned, they are the ones that fill in the spaces the map has never seen. A three-breed mix carries genetic combinations that no purebred population contains. Those combinations are where undiscovered health patterns hide. Where unexpected trait interactions live. Where the next insight about canine biology is waiting.
The dog that most genetics platforms serve worst, the weird, wonderful, unclassifiable mutt, is the dog the atlas needs most.
If your dog does not fit neatly into a breed box, that is not a limitation. That is exactly why they matter here.
What this makes possible
This is bigger than a dog profile. Here is what happens when enough dogs join, and it is more significant than most people realize.
Earlier detection.
When enough dogs occupy a genetic neighborhood, health patterns emerge. If dogs in a particular region of the atlas develop hip dysplasia at 3x the average rate, that becomes a signal, visible to every owner whose dog sits near that region, before symptoms appear. The atlas does not diagnose. It reveals patterns that you and your veterinarian can act on before they become emergencies.
Research that actually reaches you.
Universities and foundations fund dozens of canine health studies every year. Right now, finding the right dogs for those studies takes months of outreach through breed clubs and vet clinics. Most dog owners never hear about them. With the atlas, that changes. If you opt in, and only if you opt in, we will let you know when a study is looking for dogs like yours. We review every research request before it reaches you. We filter for legitimacy, institutional affiliation, and relevance to your dog. Nobody contacts you directly. We send you the opportunity. You decide whether to respond. You contact the researcher on your terms. You get the compensation. Your dog gets credited in the published science. We never share your data with anyone. We just make the introduction.
Smarter breeding.
Breeders make decisions based on limited information: health clearances on individual dogs, a pedigree, maybe an array test. The atlas shows them something they have never had: where their breeding stock sits in the full landscape of their breed's genetics. Which lines are genetically diverse. Which combinations produce the healthiest neighborhoods. Which crosses bring in the variation the breed needs.
Better nutrition.
Sniff scores dog food with a published, independent methodology that accepts no money from any brand. As the atlas grows and we learn which genetic backgrounds thrive on which nutrient profiles, the recommendations stop being generic and start being specific to your dog's biology. Not "this is good food." Instead: "dogs genetically similar to yours do well on this profile."
Veterinary intelligence.
When the atlas is dense enough, it becomes a tool veterinarians could use alongside exam results and bloodwork. "Dogs in this genetic neighborhood have an elevated incidence of this condition at this age; here is what to screen for." That is the future the atlas is building toward, one dog at a time.
Medicine that crosses species.
Dogs get the same cancers humans do. The same cardiac diseases. The same neurological conditions. Discoveries in canine genetics do not stay in canine genetics; they inform human medicine. A variant identified in Golden Retrievers with lymphoma becomes a candidate for investigation in human lymphoma. Your dog's contribution to the atlas does not just help dogs. It helps everyone.
Why it is free
Because your dog's contribution is the point. Charging for it would be charging you to help.
The atlas is built on publicly funded research data: studies funded by taxpayer dollars, foundation grants, and the participation of thousands of dog owners who gave their time and their dogs' data freely. The technology that computes your dog's position runs on open source software and public reference panels. Putting a paywall on any of that would be wrong.
Sniff sustains itself through optional products that sit beside the free science, never on top of it. A sequencing kit for owners who want their dog's whole genome. A membership for deeper personal insights. Research recruitment services for academic institutions. You never have to pay for anything. The atlas, the breed pages, the science, the methodology, all of it is free, forever, for everyone.
The industry built a system where you pay to learn about your dog and then they keep what they learned. We built the opposite. You contribute what you know. We give back everything we compute. The science belongs to everyone.
What your dog gets
A star in the atlas. A position among 14,478 research dogs. A neighborhood of the most genetically similar dogs in the system. Trait predictions based on actual loci. A page at a permanent URL that is yours to share with anyone.
A profile you can show off. Your dog, placed in a real genetic universe, with real neighbors, real data, and a real contribution to science. This is not a report that lives in a drawer. This is something you pull up at the dog park and say "look where my dog sits."
If your dog passes, their star rises into the sky above the atlas. Their data stays. Their contribution stays. Their page stays. They are remembered not as a row in a database but as a point of light in a universe they helped build. The science they contributed to continues working, long after the walks are over.
And over time, as more dogs join, your dog's page gets richer. Their neighborhood gets denser. The health patterns in their region become clearer. The science around dogs like yours deepens. Your dog's life keeps teaching.
What it takes
Five minutes. You tell us your dog's name, their breed or best guess, their size, a few optional details about their health. You share an email so we can reach you when something interesting shows up in their neighborhood, or when a study wants a dog like yours.
That is it. No payment. No commitment. No data you do not want to share.
Your dog gave you their whole life without a single condition. This is five minutes you can give back, not to a company, but to every dog that comes after yours.
