Breed library

Breeds, grounded in the canine knowledge graph.

Every card below pulls from the same data that drives the 3D atlas of 18,477 dogs. The card shows you the breed's AKC group, size, how many dogs we have in the atlas, and the breed it sits closest to genetically. Open a breed for the full picture: how genetically diverse the breed is, which morphology genes are locked in across it, which Mendelian variants run at observable frequency, and where the breed sits in the wider population.

Where a breed has nutrition coverage, a small badge points to the food guide. The genetics leads. Nutrition follows as a downstream feature, not the headline.

Sporting

2

Bred for the field. Retrievers, setters, spaniels, pointers.

Working

6

Guard, draft, rescue. Built for jobs that matter.

Herding

3

Stockwork lineage. Move animals, read intent, decide quickly.

Terrier

1

Vermin specialists. Compact, brave, willful.

Toy

3

Companion-purpose dogs. Often older and quieter than their image.

Non-Sporting

3

The catch-all group. Distinct lineages that do not fit elsewhere.

How the library works

Genetics first. Nutrition is one feature.

Each breed page leads with the population genetics computed from the atlas: how many dogs we have in the breed, how genetically diverse it is, which morphology genes are locked in across the breed and which still vary from dog to dog, the breed's closest genetic relatives, the Mendelian variants that run at observable frequency. Where we have editorial nutrition coverage, it follows after the genetics, contextualized by what's above. Every number on the page has a source.

For programmatic access: /api/v1/breeds.json is the current catalog (nutrition substrate). The per-breed genetic-neighbor data is at /api/breed/<slug>/neighbors.json. Both endpoints emit JSON under CC-BY 4.0 with permissive CORS; the LLM-discovery file at /llms.txt is the canonical entry point for AI agents grounding on Sniff content.
