Einstein Horse – World’s SMALLEST? [Get the Facts!]

After being featured on Oprah, the tiny Einstein horse became an overnight sensation. But is he truly the world’s smallest horse? Or the world’s smartest horse? If not, then who is? Let’s find out!

Einstein the miniature horse was born on April 22, 2010, at a farm in New Hampshire. With his parents being average-sized at 32 and 30 inches tall, he surprised everyone when he arrived at a mere 6 pounds and 14 inches tall, setting a world record as the smallest newborn horse.

Is Einstein still alive?

How tall is Einstein the horse now?

He is 24 inches tall at the withers and weighs approximately 80 pounds.

How old is Einstein?

He is currently 13 years old. With miniature horses having an average lifespan of 25-35 years, it is hoped that Einstein still has many years ahead of him.

What is Einstein the horse doing now?

After his appearance on Oprah, he had a fast-track fame. Einstein now has his own Facebook Page, Youtube channel, Twitter, and Instagram account.

He also has a website, Smallest Stallion, where you can find the latest media releases, games, and more.

His co-owners have written a children’s book, A Friend for Einstein, the Smallest Stallion, that features his story and includes photographs of the many other adorable creatures in his life.

No! In 2001, a dwarf miniature horse named Thumbelina was born in Missouri. She matured to only 17 inches tall and weighed 57lbs, receiving the title of world’s smallest from Guinness World Records. Sadly, Thumbelina passed away in 2008.

Prior to Thumbelina, a miniature horse named Black Beauty held the record at a height of 18.5 inches.

Who is the smallest horse in the world for 2022?

The title of smallest living horse in the world goes to Bombel (aka. “Bubble”) from Poland who stands 22 inches.

What about Koda?

Koda, another dwarf Minatrue Horse, is Australia’s smallest horse at 23 inches tall.

So what makes Einstein so special?

Unlike the Thumbelina and Bomel, the current record holders, Einstein is perfectly proportioned just like a full-size horse. Dwarf miniatures typically have undesirable conformation, according to the breed standard, and many face severe health issues due to their disproportionate body. Einstein is not a dwarf, just a pint-sized horse!

He also made headlines at only 2 months old when he suffered a spinal cord injury. Einstein broke another record as the first (and only) horse to undergo surgery by a canine specialist neurosurgeon.

The risky surgery was a success and his life was saved!

Is there another Einstein horse?

Yes. Not to be confused with the very tiny equine, there was also a thoroughbred stallion named Einstein born in 2002. Originally from Brazil, he was imported into the US where he had a successful racing career with over $2.9 million in earnings.

Is Einstein the smartest horse?

No, unfortunately neither of the Einstein horses are known for their high intelligence level, despite their names!

    Maybe world’s smallest non-dwarf??? I’ve wondered if he was premature.
