Your dog is carrying a story they can't show you.
Every gene they inherited, every trait you can see and the ones you cannot, every risk written in before they were born. They can't tell you any of it. They tell you when it is time for a walk.
The science to read that story already exists. Researchers spent careers on it and gave it away for free. But it lives in raw genotype files, behind query languages no owner speaks, on servers that will never open to you. The most detailed map of canine health ever built is real, and almost no one who loves a dog can read it.
Closing that gap is the whole reason Sniff exists.
Sniff is the honest place to understand your dog. Ask about your breed or your dog's health and you get a straight, cited answer, built on the same genetics vets and researchers actually use, an open map of 18,477 research dogs and 9.67 million canine variants. No fear, no sales pitch, just what the evidence says.
And when the evidence is thin, we tell you we don't know instead of guessing. On a subject where everyone else is selling certainty, that honesty is the whole product.
Add your dog and they get a permanent place in the atlas, a star that stays lit, even as a memorial. You get honest answers about your specific dog. And every dog added makes the map a little sharper for the next one.
You don't need a DNA test to start. Tell us what you know, the breed, the size, the shape of the ears, the way they move, and we place them as a Charted star. If you already have your dog's raw data from a test you have taken, we place them from their real genome as a Sequenced star. A dog whose person couldn't afford a test is not a lesser dog. The observation is real, and that is enough to earn a star.
Here is the part I can't stop thinking about. Dogs and people get sick in remarkably similar ways, the same genes, the same diseases, written in the same alphabet. A shepherd's degenerative myelopathy has a human cousin in ALS. A golden's cancers echo our own. Dogs may be the best natural model we have for human disease, and they are asleep on our couches.
So if we can map enough dogs honestly, breed by breed and gene by gene, we do not only help the next dog. We add to what is known about genes, about disease, about medicine, ours included. That is the dream: one open, honest map that makes life a little longer and a little kinder for dogs, and quietly teaches us about ourselves along the way.
I will be straight about where this stands. I am trying to make Sniff perfect, and I am still figuring it out. Parts are unfinished. I will get things wrong and fix them in the open.
But one line never moves: I will not tell you something is true when I am not sure of it, I will never turn a guess into a verdict, and I will never dress fear up as care or a sales pitch up as science. Sniff informs; your vet diagnoses. We describe the odds honestly; we do not predict your dog's future. If we ever cross that line, hold me to it.
- The science is free, forever.
- Your dog's data is yours. Never sold, not to brands, not to insurers, not to anyone.
- Nobody can pay for a better number. No ads, no placements, no equity in any test company.
- We never treat an estimate as a measurement. UNPROVEN on every prediction, sample size on every page.
Sniff stands on open science it did not invent: OMIA, the Vertebrate Breed Ontology, CanVAS, the Golden Retriever Lifetime Study, Darwin's Ark, and more. Every source is credited at /study and /cite; the dataset is open on Zenodo, CC-BY 4.0.
When Sniff becomes a profitable company, ten percent of every year's profit goes to shelters, rescues, and working dogs. That is the Pledge.
