’Boo’ has millions of fans and his own book

He has nearly two million fans and a book deal. But Boo isn't a reality TV star, actor or a pop singer ― he's a pet dog.

The five-year-old Pomeranian has the fame most celebrities dream of after amassing 1.79million fans on social networking site Facebook.

And Boo is also a hit with the ladies. He attracted the attention of Hollywood stars including Khloe Kardashian, who posted a picture of the dog on her blog last year and singer Ke$ha, who Tweeted that Boo was 'her new boyfriend,' Daily Mail has reported.

Since then, Boo's Facebook page, launched in 2009, has gone viral, receiving thousands of new fans a day.

His owner, who has concealed her identity and location in the U.S. and uses the pseudonym J.H Lee told Time:'My friends loved looking at pictures of him.

“We started the first Facebook page as a joke.”

Boo shot to fame when he realised the key to looking so good in photographs is a great haircut.

The canine's unique look is down to an happy accident ― his long hair was so knotted, it had to be shaved off.
