Dog Breed Health Ranking: Every Breed Graded S to E
Every dog breed graded by inherited diseases and breeding health tests — from the healthiest to the highest-risk. Based on our own health data.
Key takeaways
We graded 463 dog breeds for health from S (exceptionally healthy) to E (high risk). 79 breeds earn the top grades S or A, while 50 breeds carry elevated health risks.
- The grade combines inherited diseases, their severity and the breeding tests a breed needs.
- S and A mark the healthiest breeds; D and E mark the highest risks.
- Grades are relative to the whole population — no breed is guaranteed healthy or unhealthy.
- A responsible breeder lowers the risk substantially for almost any breed.
How we grade dog breeds
Our health grade is not an opinion — it is derived from structured data: the inherited diseases documented in a breed, their severity, and the tests that responsible breeding programs run. Placeholder data is excluded from the ranking.
Inherited diseases & severity
Which genetic and inherited conditions occur in the breed — and how severe they are.
Breeding tests level 1–3
Level 1 = club-mandated required tests, level 2 = recommended, level 3 = exemplary. The more needed, the more the breeder matters.
Grade S–E
This yields an overall grade from S (exceptionally healthy) to E (high risk), relative to the whole population.
S

Exceptionally healthy — very few known inherited issues.

Frequently asked questions
What is the healthiest dog breed?
The healthiest breeds earn a grade of S or A — they have few known inherited diseases and need comparatively few breeding tests. See the ranking above or our dedicated healthiest-breeds guide.
What does a health grade of E mean?
Grade E means high health risk. Such breeds only make sense from a thoroughly tested breeding program — or belong to the breeds worth thinking twice about.
How is the health grade calculated?
It is derived from a breed's documented inherited diseases, their severity and the required breeding tests (level 1–3). The grade is relative to the whole population of breeds.
Does a good grade mean my dog will be healthy?
No. The grade describes breed-typical risk, not the individual dog. Health-tested parents and a responsible breeder remain decisive.
