snıff
A living atlas of canine biology

The truth about your dog,
including what we still don’t know.

Add your dog to a map of canine genetics built on open science. Ask about a breed, a gene, or a diagnosis, and every answer is cited to the same sources vets and researchers use, or it says plainly that the evidence is not there yet. No fear. No sales pitch.

Why you can trust it

Built on open science, cited to the source.

Every claim on Sniff traces back to a real record you can open and read, the same OMIA entries, breed cohorts, and classification guidelines a specialist would use. Nothing here is invented.

Every dog is real

Your dog belongs here.

These are not points on a chart. Each star is a real dog whose DNA helped build what we know. Add yours and it takes a permanent place among them, and the more of their story you choose to share, the more they can help the dogs who come after.

How it works

Open science, real dogs, and yours, in one atlas.

The sources
Cited, open, checkable.
OMIA · ClinVar · Ensembl · Dog10K
Real dogs
18,477 research dogs, and yours.
The atlas
One connected map
Every breed, gene, disease, and variant, tied to real dogs, traceable to its source, and honest about what nobody has studied yet.
For owners
What your breed is prone to, cited to the study.
For vets and scientists
17,178 dog-to-human ortholog links, and 16,630 gaps named by cause, not guessed.
For medicine
107 human disease genes with no dog model yet, named.
Add your dog and they join it. Share their story now, their DNA when you’re ready, and they make the next dog’s answer better.
The pledge

Independence is the product.

No ads. No sponsorships. No commissions. Your dog is not the product, and neither are you.

The living atlas

A living atlas of every dog.

A whole Record tonight. DNA when you have a file.

18,477 dogs already here.

Layout is illustrative. Positions are not genetic.

What a living Record can answer
ChartedA whole Record. No DNA file yet.
Ask  “She might be a herding mix. Is a heartworm preventative safe for her?”

Some herding breeds carry MDR1 at a cited rate. A vet can choose safer drugs when the variant is known.OMIA 001402-9615

That rate is about dogs like hers, not a verdict about this dog.

Honest gapCharted cannot say whether she carries it. That takes a file. The star still goes on the map, and the cited breed page sits beside her name.

The room we keep

When a dog passes, their star stays. That is a different room.

We keep them
Pax, a Corgi and Rottweiler mix
Pax
Corgi and Rottweiler mix · 11 years
Charted

When a dog passes, their star stays in the atlas.

Pax’s page is kept in full, his photos, his story, and the record his owner built, beside the cited biology of a Corgi and a Rottweiler.

That biology includes degenerative myelopathy, documented in Corgis and studied in human ALS.OMIA 000263-9615

Without a DNA test, we never named which variants Pax himself carried, and his page says so.

A place that stays lit.
