Dog Breed API – Data on 650+ Breeds
A developer-friendly dog breed API with structured JSON on 650+ dog breeds and mixes: size, temperament, lifespan, breed characteristics and vet-reviewed health data. Free API key, no credit card required.
650+ breeds and mixes
Recognised breeds plus common mixes, each returned as structured, consistent JSON you can drop straight into your app.
Vet-reviewed data
Health predispositions, dietary guidance and breed characteristics reviewed by veterinary professionals, not scraped from forums.
Built for developers
Simple REST endpoints, breed search, breed images and reference docs with copy-paste examples.
Everything your app needs to know about a breed
Weight and height ranges, life expectancy, temperament and exercise needs, alongside breed imagery. Deeper vet-reviewed layers such as health predispositions and dietary guidance are available for teams building insurance, pet health and retail products.
From side project to production
Start free for prototypes, classes and hackathons, then scale to commercial tiers when you need advanced health data and higher limits. The same breed dataset powers real products across pet insurance, retail and health apps.
Free tier
A generous free tier for prototypes, students and side projects. No credit card to get started.
JSON + images together
Breed data and dog photos from one API, so you never need to stitch together multiple sources.
Commercial-grade data
The same dataset is licensed by pet businesses, so you get production-quality data from day one.
