A horse gracefully steps across the grassy field alongside its rider.

However, its tail is exceptionally long.

It seems to have no end in sight no matter how you look at it.

The star of the show is a mare named "Jenny" living in Ohio, United States.

Her tail hair reached a whopping 412.62 cm, setting a Guinness World Record.

She reportedly grew her tail hair for a full 7 years.

It takes an average of 4 to 5 hours just to thoroughly wash, dry, and braid the tail hair about once a month.

The owner's dedication is even more astounding.
