The largest horse ever recorded was a stallion named Dr Le Gear who stood 21 hands or 84 inches What breed of Gear?

There is no horse named "Dr Le Gear" listed as the largest horse ever recorded. It is likely you are referring to a different horse or a misremembered name.

There are many horses that have been recorded as exceptionally tall.

Here are a few things to consider:

* Height is recorded in hands, not inches: A hand is 4 inches, so a horse that stands 21 hands tall is actually 84 inches tall.

* The world record for the tallest horse ever recorded belongs to a Shire horse named Sampson. Sampson was recorded at 7 feet 2 inches (21.8 hands) tall.

* "Dr Le Gear" might be a misremembered name. There is no widely known horse with that name that holds the record for height.

If you have any more information about the horse you are referring to, I may be able to help you find it.
