Sovereign was once neglected and underweight before he was rescued by his new owner Paul Evans. As a result, he grew bigger and is now hailed as Britain's tallest horse, as he stands 10 feet tall.

Despite its sad condition four years ago, Sovereign continues to grow taller and taller! The previous owner of the horse kept him inside a small shed and neglected to feed him, which resulted in him being malnourished.

Since the horse is now well taken care of, he is in good health and turned into a giant horse. Sovereign is now set to overtake the current world record of the world's tallest horse.

The six-year-old shire horse measures just under 21 hands from his hoof to the withers at the bottom of his neck – the equivalent of just under seven ft- but the top of his head stands at a staggering 10 ft above the ground, according to the YouTube video's description. 

“I never believed he would grow into such a monster – and he’s still growing. He’s wonderful and I’m delighted I bought him. Because he’s still young he’s still got years of growth in front of him,” Evans said, Yahoo! News reported.

Sovereign currently lives at Green Farm in Caverswall, Staffordshire, where Evans’ two other shire horses, Poppy and Sovereign’s half-sister Ruby, also reside.
