13. Tiny Filly Horse
Found In: All Over
Estimated Cost: $700*
These newborn horses, often called foals, are smaller than the average human being, standing between 15 and 22 inches tall at birth. This image shows a puppy and a tiny horse side by side, with little to no size difference between them.
But horses grow quite quickly; by the time they turn a year old, their height has nearly reached adult proportions. Therefore, this size won’t survive very long if you’re looking to buy little baby horses just because they’re so cute.
