Healthiest horses (fewest costly conditions)
Chart: the six top-ranked horses by health conditions — taller bars rank higher on this metric.
What this ranking shows
Across 20 horses, health conditions ranges from 2 to 4 — a 2.0× spread, with a median around 3. The Tennessee Walking Horse leads at 2 tracked, while the Shetland Pony sits at the far end. Rounding out the top three are the Mustang (2 tracked) and the Morgan (3 tracked). Most of the gap comes down to three things: body size (which sets how much a horse eats and its medication doses), breed health risk (which sets insurance premiums and likely vet bills), and lifespan (which multiplies every recurring annual cost). Use the sorter below to re-rank by your own budget, home size and grooming tolerance.
