The owner of a 3-year-old horse from Tennessee is hoping to register his animal for Guinness World Record as she is 81 inches tall at this age and still has a lot of scope to grow.

Officially named Jenson Diplomat Tina, the English Shire horse is already so big in her teenage years that she can easily break record of world's tallest horse Radar, who stands at 19 hands, 3 1/2 inches tall, or 79 1/2 inches.

AP reports that Tina, who weighs 1,600 pounds, now measures 81 inches at the withers, the equestrian term for the top of the shoulder. The owner, Jim Williams is hoping Tina still has at least two years of growth and could reach 21 hands equivalent to 7 feet, or 84 inches, measured at the withers.

Tina will be measured later this month at her owner's bed and breakfast in Niota, about 65 miles northeast of Chattanooga.
