the world's smallest horse , its fantastic

 THE world's smallest horse is getting ready to celebrate his big day — with the release of his first book.

Little Einstein the miniature stallion may be just 20 inches tall, but that hasn't stopped him becoming a huge star.

The tiny horse, from New Hampshire in the US, has already captured the hearts of millions, including celebrities like Oprah Winfrey, who invited him on her hit TV show.

But it is friends a bit closer to home that the small steed struggles with.

And his quest to find a pal tiny enough to play with him has been made into book called A Friend for Einstein — which is due to be released on his first birthday next month.

Einstein's owners Dr Rachel Wagner and Charlie Cantrell have struggled to find a mini playmate for the little pony.

He is so tiny they worry a bigger horse could hurt or crush him, but no-one has told Einstein that.

He has already made firm friends with Playboy, a towering full-sized Stallion owned by a neighbour.

And he has befriended Charlie and Rachel's Boxer dog Lilly and a St. Bernard called Heather.

Owner Charlie said: "Playboy is owned by a young lady who lives next to our farm and Einstein sometimes meets him to have a head sniff and a simple hello.

"You see the adorable thing about Einstein is that he doesn't seem to be too aware of his height at all."

He added: "He approaches Lilly and Playboy just like he was a fully grown stallion. He rears up and huffs and gallops around."

The very miniature horse sparked massive public interest when he was born, with 4,000 visitors queuing to see the 14-inch high newborn.
